The compatible string for Rockchip RK3288 is wrongly provided in the
'enum' item, in addition to the subsequent 'const', which allows the
usage of an incorrect specification:
compatible = "rockchip,rk3288-timer", "rockchip,rk3288-timer";
As the rk3288 string is also specified in the top-most 'const' item, the
binding already allows the usage of the correct variant:
compatible = "rockchip,rk3288-timer";
Drop the unwanted rk3288 entry from the enum.

Merge Qualcomm MSM timer bindings into watchdog, because the timer
compatibles are already included here and the hardware is quite similar.
While converting the MSM timer bindings, adjust clock-frequency
property to take only one frequency, instead of two, because:
1. DT schema does not allow to frequencies,
2. The Linux timer driver reads only first frequency.

BCA is a big set / family of Broadcom devices sharing multiple hardware
blocks. One of them is timer that actually exists in two versions. It's
a part of TWD MFD block.
Add binding for it so SoCs can be properly described. Linux (and
probably any other OS) doesn't really seem to need a driver for it. it
may be needed for bootloaders (e.g. U-Boot) though. Especially for SoCs
with CPUs other than Cortex-A9 (which contains arch timers).

Since the Armv7 and Armv8 architected timers are compatible, it is valid
to expose a devicetree node with compatible string "arm,armv8-timer"
followed by "arm,armv7-timer". For example a 32-bit guest running on a
64-bit machine may look for the v7 string even though the hardware is v8.
VMMs such as QEMU and kvmtool have been using this compatible string for
some time. Clean up the compatible list a little and add the dual
option.

The ARTPEC-8 has an MCT with 4 global and 8 local timer interrupts.
The SoC has a quad-core Cortex-A53 and a single-core Cortex-A5 which
share one MCT with one global and eight local timers. The Cortex-A53
and Cortex-A5 do not have cache-coherency between them, and therefore
run two separate kernels.
The Cortex-A53 boots first and starts the global free-running counter
and also registers a clock events device using the global timer. (This
global timer clock events is usually replaced by arch timer clock events
for each of the cores.)
When the A5 boots (via the A53), it should not use the global timer
interrupts or write to the global timer registers. This is because even
if there are four global comparators, the control bits for all four are
in the same registers, and we would need to synchronize between the
cpus. Instead, the global timer FRC (already started by the A53) should
be used as the clock source, and one of the local timers which are not
used by the A53 can be used for clock events on the A5.
To support this hardware, add a compatible for the MCT as well as two
new properties to describe the hardware-mandated sharing of the FRC and
dedicating local timers to specific processors.

As usual, the bulk of the changes for the SoC tree are devicetree file
updates, and most of these changes are for 64-bit embedded machines.
As before, there are a ton of style cleanups, and additional hardware
support for existing machines.
Looking only at the new SoC, the notable additions are:
- A whole family of Broadcom broadband SoCs, both 32-bit and 64-bit:
BCM63178, BCM63158, BCM4912, BCM6858, BCM6878, BCM6846, BCM63146,
BCM6856, BCM6855, BCM6756, BCM63148, and BCM6813.
Each SoC comes with a corresponding reference board.
- The new NXP i.MX93 SoC, the follow-up to the popular i.MX6 and
i.MX8 embedded SoCs, now using Cortex-A55 cores and the
Ethos-U65 NPU.
- Qualcomm Snapdragon 8cx Gen3 (SC8280XP), the current high end
of Arm based Laptop SoCs, and its automotive cousin, the
SA8540P. The SC8280XP is used in the Lenovo Thinkpad X13s
laptop that also gets added here in addition to the reference
boards.
- Allwinner H616, a newer version of the H6 SoC, targeted at
Set-top-box applications. It comes with dts files for the
Orange Pi zero2 single-board computer and the X96 Mate
set-top-box
- Marvell Prestera 98DX2530 (AlleyCat5), a network switch chip
in the Armada SoC family based on the Cortex-A55 core.
New machines based on previously supported SoCs include:
- Several new machines on NXP i.MX platforms: multiple Toradex
Colibri boards using the "Iris" and "Ixora" carriers,
DH electronics i.MX8M Plus DHCOM and PDK2, TQ-Systems
TQMa8MPQL, and phytech phyBOARD-Polis-i.MX8MM.
- Google Chameleon v3 FPGA board based on Intel Arria10 and
Stratix 10 Software Virtual platform, both in the SoCFPGA
platform.
- Two new wireless devices based on Broadcom SoCs:
The Asus GT-AX6000 Router and the Cisco Meraki MR26 access point
- Improved Chromebook support for both the Mediatek and Qualcomm
SoC families brought added machines: Acer Chromebook 514 (MT8192),
Acer Chromebook Spin 513 (MT8195) and a couple of SC7180 based
machines including the Lenovo IdeaPad Chromebook Duet 3.
- Xiaomi Mi Mix2s, LG G7 and LG V35 are mobile phones based on
Qualcomm SDM845, while Mi 5s Plus is based on MSM8996.
- Finally, there are a few development board on other chips:
PCB8309 (Microchip lan966x), Radxa Rock Pi S (Rockchips RK3308)
DH DRC Compact (ST STM32MP1) and Inforce IFC6560 (Qualcomm

The Tegra186 timer provides ten 29-bit timer counters and one 32-bit
timestamp counter. The Tegra234 timer provides sixteen 29-bit timer
counters and one 32-bit timestamp counter. Each NV timer selects its
timing reference signal from the 1 MHz reference generated by USEC,
TSC or either clk_m or OSC. Each TMR can be programmed to generate
one-shot, periodic, or watchdog interrupts.

Patch series from Nick Hawkins:
"The GXP is the HPE BMC SoC that is used in the majority of HPE current
generation servers. Traditionally the asic will last multiple
generations of server before being replaced.
Info about SoC:
HPE GXP is the name of the HPE Soc. This SoC is used to implement many
BMC features at HPE. It supports ARMv7 architecture based on the Cortex
A9 core. It is capable of using an AXI bus to which a memory controller
is attached. It has multiple SPI interfaces to connect boot flash and
BIOS flash. It uses a 10/100/1000 MAC for network connectivity. It has
multiple i2c engines to drive connectivity with a host infrastructure.
The initial patches enable the watchdog and timer enabling the host to
be able to boot."

The asm-generic tree contains three separate changes for linux-5.19:
- The h8300 architecture is retired after it has been effectively
unmaintained for a number of years. This is the last architecture we
supported that has no MMU implementation, but there are still a few
architectures (arm, m68k, riscv, sh and xtensa) that support CPUs with
and without an MMU.
- A series to add a generic ticket spinlock that can be shared by most
architectures with a working cmpxchg or ll/sc type atomic, including
the conversion of riscv, csky and openrisc. This series is also a
prerequisite for the loongarch64 architecture port that will come as
a separate pull request.
- A cleanup of some exported uapi header files to ensure they can be
included from user space without relying on other kernel headers.

There are minor updates to SoC specific drivers for chips by Rockchip,
Samsung, NVIDIA, TI, NXP, i.MX, Qualcomm, and Broadcom. Noteworthy
driver changes include:
- Several conversions of DT bindings to yaml format.
- Renesas adds driver support for R-Car V4H, RZ/V2M and RZ/G2UL SoCs.
- Qualcomm adds a bus driver for the SSC (Snapdragon Sensor Core),
and support for more chips in the RPMh power domains and the soc-id.
- NXP has a new driver for the HDMI blk-ctrl on i.MX8MP.
- Apple M1 gains support for the on-chip NVMe controller, making it

Let's add compatible for ti,am654-timer for TI am64, am65 and j72 SoCs.
As the timer hardware is the same between am64, am65 and j72 we use the
compatible name for the earliest SoC with this timer.
The timer interrupts are not routable for the operating system for some
timers on am6. Let's make sure the interrupts are configured for the
timers on all other SoCs.

Let's update the TI timer binding to use yaml. As this binding is specific
to the TI dual-mode timers also known as dm-timers, let's use file name
ti,timer-dm.yaml to avoid confusion with other timers.
We add checks for the deprecated ti,hwmods property as done for other TI
device driver bindings earlier.
We also correct the issue with the old binding that was out of date for
several properties.
The am43 related timers are undocumented, but compatible with the am3
timers. Let's add the am43 timers too.
The dm814 and dm816 timers are missing, let's add them.
Some timers on some SoCs are dual mapped, like the ABE timers on omap4
and 5. The reg property maxItems must be updated to 2.
The timer clocks can be managed by the parent interconnect target module
with no clocks assigned for the timer node. And in some cases, the SoC may
need to configure additional system clock for the timer in addition to the
functional clock.
The clock names are optional and not specific to the comptible property.
For example, dra7 timers on l3 interconnect do not need clock-names, while
the timers on dra7 l4 interconnect need them with both being compatible
with ti,omap5430-timer.

Most of the Samsung Exynos SoCs use almost the same Multi-Core Timer
block, so only two compatibles were used so far (for Exynos4210 and
Exynos4412 flavors) with Exynos4210-one being used in most of the SoCs.
However the Exynos4210 flavor actually differs by number of interrupts.
Add new compatibles, maintaining backward compatibility with Exynos4210,
and constraints for number of interrupts. This allows to exactly match
the Exynos MCT hardware.

This adds a binding for the Xilinx LogiCORE IP AXI Timer. This device is a
"soft" block, so it has some parameters which would not be configurable in
most hardware. This binding is usually automatically generated by Xilinx's
tools, so the names and values of some properties should be kept as they
are, if possible. In addition, this binding is already in the kernel at
arch/microblaze/boot/dts/system.dts, and in user software such as QEMU.
The existing driver uses the clock-frequency property, or alternatively the
/cpus/timebase-frequency property as its frequency input. Because these
properties are deprecated, they have not been included with this schema.
All new bindings should use the clocks/clock-names properties to specify
the parent clock.
Because we need to init timer devices so early in boot, we determine if we
should use the PWM driver or the clocksource/clockevent driver by the
presence/absence, respectively, of #pwm-cells. Because both counters are
used by the PWM, there is no need for a separate property specifying which
counters are to be used for the PWM.

- Mediatek mt6582 tablet platform with the Prestigio PMT5008 3G tablet
- Microchip Lan966 networking SoC and it evaluation board

over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91, Allwinner,
i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and Broadcom.
Samsung has a rework for its pinctrl schema that is a bit tricky and
requires driver changes to be included here.

Pull ARM devicetree updates from Arnd Bergmann:
"After a somewhat quiet 5.17 release, the size of the DT changes is a
bit larger again. There are nine new SoC that get added, all of them
related to existing platforms:
- Airoha (formerly Mediatek/EcoNet) EN7523 networking SoC and EVB
- Mediatek mt6582 tablet platform with the Prestigio PMT5008 3G
tablet
- Microchip Lan966 networking SoC and it evaluation board
- Qualcomm Snapdragon 625/632 midrange phone SoCs, with the LG Nexus
5X and Fairphone FP3 phones
- Renesas RZ/G2LC and RZ/V2L general-purpose embedded SoCs, along
with their evaluation boards

Support for additional functionality in existing dts files is added
all over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91,
Allwinner, i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and
Broadcom.
Samsung has a rework for its pinctrl schema that is a bit tricky and
requires driver changes to be included here.
A few more platforms only have smaller cleanups and DT Schema fixes,
this includes SoCFPGA, ux500, ixp4xx, STi, Xilinx Zynq, LG, and Juno.
The new machines are really too many to list, but I'll do it anyway:
Allwinner:
- A20-Marsboard development board

- Amediatek X96-AIR (Amlogic S905X3)
- CYX A95XF3-AIR (Amlogic S905X3)
- Haochuangy H96-Max (Amlogic S905X3)
- Amlogic AQ222 (Amlogic S4)
- OSMC Vero 4K+ (Amlogic S905D)
Arm Juno:
- Separate DT depending on SCMI firmware version
Aspeed:
- Quanta S6Q BMC (AST2600)
- ASRock ROMED8HM3 (AST2500)
Broadcom:
- Raspberry Pi Zero 2 W
Marvell MVEBU/Armada:

- Ctera C200 V2 NAS (armada-370)
Mstar:
- DongShanPiOne, a low-end embedded board
- Miyoo Mini handheld game console
NXP i.MX:
- Numerous i.MX8M Mini based boards in even more variations, but
none based on other SoCs this time:
Protonic PRT8MM, emCON-MX8M Mini, Toradex Verdin, and
Gateworks GW7903
Qualcomm:
- Google Herobrine R1 Chromebook platform (Snapdragon 7c Gen 3)
- SHIFT6mq phone (Snapdragon 845)
- Samsung Galaxy Book2 (Snapdragon 850)
- Snapdragon 8 Gen 1 Hardware Development Kit
TI OMAP:
- SanCloud BeagleBone Enhanced WiFi
Rockchip:
- Pine64 PineNote ereader tablet (rk356x)

There are three sets of updates for 5.18 in the asm-generic tree:
- The set_fs()/get_fs() infrastructure gets removed for good. This
was already gone from all major architectures, but now we can
finally remove it everywhere, which loses some particularly
tricky and error-prone code.
There is a small merge conflict against a parisc cleanup, the
solution is to use their new version.
- The nds32 architecture ends its tenure in the Linux kernel. The
hardware is still used and the code is in reasonable shape, but
the mainline port is not actively maintained any more, as all
remaining users are thought to run vendor kernels that would never
be updated to a future release.
There are some obvious conflicts against changes to the removed
files.
- A series from Masahiro Yamada cleans up some of the uapi header
files to pass the compile-time checks.

The nds32 architecture, also known as AndeStar V3, is a custom 32-bit
RISC target designed by Andes Technologies. Support was added to the
kernel in 2016 as the replacement RISC-V based V5 processors were
already announced, and maintained by (current or former) Andes
employees.
As explained by Alan Kao, new customers are now all using RISC-V,
and all known nds32 users are already on longterm stable kernels
provided by Andes, with no development work going into mainline
support any more.
While the port is still in a reasonably good shape, it only gets
worse over time without active maintainers, so it seems best
to remove it before it becomes unusable. As always, if it turns
out that there are mainline users after all, and they volunteer
to maintain the port in the future, the removal can be reverted.

The number of interrupts lacks an upper bound, thus assuming one,
causing properly grouped "interrupts-extended" properties to be flagged
as an error by "make dtbs_check".

Less than some other releases, but there's been significant work on
cleanups, refactorings and device enabling on existing platforms.
A non-exhaustive list of new material:
- Refactoring of BCM2711 dtsi structure to add support for the Raspberry Pi 400
- Rockchip: RK3568 SoC and EVB, video codecs for rk3036/3066/3188/322x
- Qualcomm: SA8155p Automotive platform (SM8150 derivative),
SM8150/8250 enhancements and support for Sony Xperia 1/1II and 5/5II
- TI K3: PCI/USB3 support on AM64-sk boards, R5 remoteproc definitions
- TI OMAP: Various cleanups

"Like always, the DT branch is sizable. There are numerous additions
and fixes to existing platforms, but also a handful of new ones
introduced. Less than some other releases, but there's been
significant work on cleanups, refactorings and device enabling on
existing platforms.
A non-exhaustive list of new material:
- Refactoring of BCM2711 dtsi structure to add support for the
Raspberry Pi 400
- Rockchip: RK3568 SoC and EVB, video codecs for
rk3036/3066/3188/322x
- Qualcomm: SA8155p Automotive platform (SM8150 derivative),
SM8150/8250 enhancements and support for Sony Xperia 1/1II and
5/5II
- TI K3: PCI/USB3 support on AM64-sk boards, R5 remoteproc
definitions
- TI OMAP: Various cleanups
- Tegra: Audio support for Jetson Xavier NX, SMMU support on Tegra194

If a property has an 'items' list, then a 'minItems' or 'maxItems' with the
same size as the list is redundant and can be dropped. Note that is DT
schema specific behavior and not standard json-schema behavior. The tooling
will fixup the final schema adding any unspecified minItems/maxItems.
This condition is partially checked with the meta-schema already, but
only if both 'minItems' and 'maxItems' are equal to the 'items' length.
An improved meta-schema is pending.

Convert the Renesas H8/300 Timer Pulse Unit Device Tree binding
documentation to json-schema.
Correct clock-names, as "peripheral_clk" is the name of the supplier,
and all users use "fck".
Note that there are two different bindings for the TPU, both using
"renesas,tpu": this one for using the TPU as a clock source (used on
H8/300), and a second use for using the TPU as a PWM controller (used on
ARM). To avoid conflicts, both bindings are marked with the appropriate
"select" logic, to check for the absence respectively presence of the
"#pwm-cells" property.

but it boots and can use framebuffer and serial console over a special
USB cable.
Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe)

There are six new SoCs added this time. Apple M1 and Nuvoton WPCM450
have separate branches because they are new SoC families that require
changes outside of device tree files. The other four are variations of
already supported chips and get merged through this branch:
- STMicroelectronics STM32H750 is one of many variants of STM32
microcontrollers based on the Cortex-M7 core. This is particularly
notable since we rarely add support for new MMU-less chips
these days. In this case, the board that gets added along with
the platform is not a SoC reference platform but the "Art Pi"
(https://art-pi.gitee.io/website/) machine that was originally design
for the RT-Thread RTOS.
- NXP i.MX8QuadMax is a variant of the growing i.MX8 embedded/industrial
SoC family, using two Cortex-A72 and four Cortex-A53 cores. It
gets added along with its reference board, the "NXP i.MX8QuadMax
Multisensory Enablement Kit".
- Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon 7c)
that is used in some Chromebooks and Windows laptops. Only a reference
board is added for the moment.
- TI AM64x Sita4ra is a new version of the K3 SoC family for industrial
control, motor control, remote IO, IoT gateway etc., similar to the
older AM65x family. Two reference machines are added alongside.
Among the newly added machines, there is a very clear skew towards 64-bit
machines now, with 12 32-bit machines compared to 23 64-bit machines. The
full list sorted by SoC is:
- ASpeed AST2500 BMC: ASRock E3C246D4I Xeon server board
- Allwinner A10: Topwise A721 Tablet
- Amlogic GXL: MeCool KII TV box
- Amlogic GXM: Mecool KIII, Minix Neo U9-H TV boxes
- Broadcom BCM4908: TP-Link Archer C2300 V1 router
- MStar SSD202D: M5Stack UnitV2 camera
- Marvell Armada 38x: ATL-x530 ethernet switch
- Mediatek MT8183 Chromebooks: Lenovo 10e, Acer Spin 311,
Asus Flip CM3, Asus Detachable CM3
- Mediatek MT8516/MT8183: OLogic Pumpkin Board
- NXP i.MX7: reMarkable Tablet
- NXP i.MX8M: Kontron pitx-imx8m, Engicam i.Core MX8M Mini
- Nuvoton NPCM730: Quanta GBS BMC
- Qualcomm X55: Telit FN980 TLB SoM, Thundercomm TurboX T55 SoM
- Qualcomm MSM8998: OnePlus 5/5T phones
- Qualcomm SM8350: Snapdragon 888 Mobile Hardware Development Kit
- Rockchip RK3399: NanoPi R4S board
- STM32MP1: Engicam MicroGEA STM32MP1 MicroDev 2.0 and SOM,
EDIMM2.2 Starter Kit, Carrier, SOM
- TI AM65: Siemens SIMATIC IOT2050 gateway
There is notable work going into extending already supported machines
and SoCs:
- ASpeed AST2500
- Allwinner A23, A83t, A31, A64, H6
- Amlogic G12B
- Broadcom BCM4908
- Marvell Armada 7K/8K/CN91xx
- Mediatek MT6589, MT7622, MT8173, MT8183, MT8195
- NXP i.MX8Q, i.MX8MM, i.MX8MP
- Qualcomm MSM8916, SC7180, SDM845, SDX55, SM8350
- Renesas R-Car M3, V3U
- Rockchip RK3328, RK3399
- STEricsson U8500
- STMicroelectronics STM32MP141
- Samsung Exynos 4412
- TI K3-AM65, K3-J7200
- TI OMAP3
Among the treewide cleanups and bug fixes, two parts stand out:
- There are a number of cleanups for issues pointed out by 'make
dtbs_check' this time, and I expect more to come in the future as we
increasingly check for regressions.
- After a change to the MMC subsystem that can lead to unpredictable
device numbers, several platforms add 'aliases' properties for these
to give each MMC controller a fixed number.

Add compatible strings to support the system timer, clocksource, OST,
watchdog and PWM blocks of the JZ4760 and JZ4760B SoCs.
Newer SoCs which behave like the JZ4760 or JZ4760B now see their
compatible string require a fallback compatible string that corresponds
to one of these two SoCs.

Not all platforms provide the same set of timers/interrupts, and Linux
only needs one (plus kvm/guest ones); some platforms are working around
this by using dummy fake interrupts. Implementing interrupt-names allows
the devicetree to specify an arbitrary set of available interrupts, so
the timer code can pick the right one.
This also adds the hyp-virt timer/interrupt, which was previously not
expressed in the fixed 4-interrupt form.

I have a handful of new RISC-V related patches for this merge window:
* A check to ensure drivers are properly using uaccess. This isn't
manifesting with any of the drivers I'm currently using, but may catch
errors in new drivers.
* Some preliminary support for the FU740, along with the HiFive
Unleashed it will appear on.
* NUMA support for RISC-V, which involves making the arm64 code generic.
* Support for kasan on the vmalloc region.
* A handful of new drivers for the Kendryte K210, along with the DT
plumbing required to boot on a handful of K210-based boards.
* Support for allocating ASIDs.
* Preliminary support for kernels larger than 128MiB.
* Various other improvements to our KASAN support, including the
utilization of huge pages when allocating the KASAN regions.
We may have already found a bug with the KASAN_VMALLOC code, but it's
passing my tests. There's a fix in the works, but that will probably
miss the merge window.

Properties in if/then schemas weren't getting checked by the meta-schemas.
Enabling meta-schema checks finds several errors.
The use of an 'items' schema (as opposed to the list form) is wrong in
some cases as it applies to all entries. 'contains' is the correct schema
to use in the case of multiple entries.

The c6x architecture was added to the kernel in 2011 at a time when
running Linux on DSPs was widely seen as the logical evolution.
It appears the trend has gone back to running Linux on Arm based SoCs
with DSP, using a better supported software ecosystem, and having better
real-time behavior for the DSP code. An example of this is TI's own
Keystone2 platform.
The upstream kernel port appears to no longer have any users. Mark
Salter remained avaialable to review patches, but mentioned that
he no longer has access to working hardware himself. Without any
users, it's best to just remove the code completely to reduce the
work for cross-architecture code changes.
Many thanks to Mark for maintaining the code for the past ten years.

The NPCM750 Timer/Watchdog Controller has multiple interrupt lines,
connected to multiple timers. The driver uses timer 0 for timer
interrupts, so the interrupt line corresponding to timer 0 should be
specified in DT.
I removed the mention of "flags for falling edge", because the timer
controller uses high-level interrupts rather than falling-edge
interrupts, and whether flags should be specified is up the interrupt
controller's DT binding.

DT properties which can have multiple entries need to specify what the
entries are and define how many entries there can be. In the case of
only a single entry, just 'maxItems: 1' is sufficient.
Add the missing entry constraints. These were found with a modified
meta-schema. Unfortunately, there are a few cases where the size
constraints are not defined such as common bindings, so the meta-schema
can't be part of the normal checks.

In cases where we don't reference another schema, 'additionalProperties'
can be used instead. This is preferred for now as 'unevaluatedProperties'
support isn't implemented yet.
In a few cases, this means adding some missing property definitions of
which most are for SPI bus properties. 'unevaluatedProperties' is not going
to work for the SPI bus properties anyways as they are evaluated from the
parent node, not the SPI child node.

The Exynos Multi Core Timer driver requires two clocks. This was never
documented in the binding. Add it to fix dtschema warnings like:
arch/arm64/boot/dts/exynos/exynos5433-tm2.dt.yaml: timer@101c0000:
'clock-names', 'clocks' do not match any of the regexes: 'pinctrl-[0-9]+'

This converts the DT binding documentation for the ARM SP-804 timer IP
over to json-schema.
Most properties are just carried over, the clocks property requirement
(either one or three clocks) is now formalised and enforced.
As the former binding didn't specify clock-names, and there is no
common name used by the existing DTs, I refrained from adding them in
detail (just allowing the property).
The requirement for the APB clock is enforced by the primecell binding
already.

json-schema versions draft7 and earlier have a weird behavior in that
any keywords combined with a '$ref' are ignored (silently). The correct
form was to put a '$ref' under an 'allOf'. This behavior is now changed
in the 2019-09 json-schema spec and '$ref' can be mixed with other
keywords. The json-schema library doesn't yet support this, but the
tooling now does a fixup for this and either way works.
This has been a constant source of review comments, so let's change this
treewide so everyone copies the simpler syntax.
Scripted with ruamel.yaml with some manual fixups. Some minor whitespace
changes from the script.

Setting 'additionalProperties: false' is frequently omitted, but is
important in order to check that there aren't extra undocumented
properties in a binding.
Ideally, we'd just add this automatically and make this the default, but
there's some cases where it doesn't work. For example, if a common
schema is referenced, then properties in the common schema aren't part
of what's considered for 'additionalProperties'. Also, sometimes there
are bus specific properties such as 'spi-max-frequency' that go into
bus child nodes, but aren't defined in the child node's schema.
So let's stick with the json-schema defined default and add
'additionalProperties: false' where needed. This will be a continual
review comment and game of wack-a-mole.

Core:
- Consolidation of the vDSO build infrastructure to address the
difficulties of cross-builds for ARM64 compat vDSO libraries by
restricting the exposure of header content to the vDSO build.
This is achieved by splitting out header content into separate
headers. which contain only the minimaly required information which is
necessary to build the vDSO. These new headers are included from the
kernel headers and the vDSO specific files.
- Enhancements to the generic vDSO library allowing more fine grained
control over the compiled in code, further reducing architecture

Pull timekeeping and timer updates from Thomas Gleixner:
"Core:
- Consolidation of the vDSO build infrastructure to address the
difficulties of cross-builds for ARM64 compat vDSO libraries by
restricting the exposure of header content to the vDSO build.
This is achieved by splitting out header content into separate
headers. which contain only the minimaly required information which
is necessary to build the vDSO. These new headers are included from
the kernel headers and the vDSO specific files.
- Enhancements to the generic vDSO library allowing more fine grained
control over the compiled in code, further reducing architecture
specific storage and preparing for adopting the generic library by
PPC.
- Cleanup and consolidation of the exit related code in posix CPU
timers.

On many arm64 qcom device trees, running `make dtbs_check` yells:
timer@17c20000: #size-cells:0:0: 1 was expected
It appears that someone was trying to assert the fact that sub-nodes
describing frames would never have a size that's more than 32-bits
big. That does indeed appear to be true for all cases I could find.
Currently many arm64 qcom device tree files have a #address-cells and
about in commit bede7d2dc8 ("arm64: dts: qcom: sdm845: Increase
address and size cells for soc"). That means the only way we can
shrink them down is to use a non-empty ranges.
Since forever it has said in "writing-bindings.txt" to "DO use
non-empty 'ranges' to limit the size of child buses/devices". I guess
we should start listening to it.
I believe (but am not certain) that this also means that we should use
"ranges" to simplify the "reg" of our sub devices by specifying an
offset. Let's update the example in the bindings to make this
obvious.

The R-Car Gen3 SoCs so far come with a total for 4 on-chip CMT devices:
- CMT0
- CMT1
- CMT2
- CMT3
CMT0 includes two rather basic 32-bit timer channels. The rest of the on-chip
CMT devices support 48-bit counters and have 8 channels each.
Based on the data sheet information "CMT2/3 are exactly same as CMT1"
it seems that CMT2 and CMT3 now use the CMT1 compat string in the DTSI.
Clarify this in the DT binding documentation by describing R-Car Gen3 and
RZ/G2 CMT1 as "48-bit CMT devices".

CMT0, CMT2, CMT3 and CMT4. They all contain a single channel and are
quite similar however some minor differences still exist:
- "Counter input clock" (clock input and on-device divider)
One example is that RCLK 1/1 is supported by CMT2, CMT3 and CMT4.
- "Wakeup request" (supported by CMT0 and CMT2)
Because of this one unique compat string per CMT device is selected.

We continue to see a lot of new material. I've highlighted some of it
below, but there's been more beyond that as well.
One of the sweeping changes is that many boards have seen their ARM Mali
GPU devices added to device trees, since the DRM drivers have now been
merged.
So, with the caveat that I have surely missed several great
contributions, here's a collection of the material this time around:
New SoCs:
- Mediatek mt8183 (4x Cortex-A73 + 4x Cortex-A53)
- TI J721E (2x Cortex-A72 + 3x Cortex-R5F + 3 DSPs + MMA)
- Amlogic G12B (4x Cortex-A73 + 2x Cortex-A53)
New Boards / platforms:
- Aspeed BMC support for a number of new server platforms
- Kontron SMARC SoM (several i.MX6 versions)
- Novtech's Meerkat96 (i.MX7)
- ST Micro Avenger96 board
- Hardkernel ODROID-N2 (Amlogic G12B)
- Purism Librem5 devkit (i.MX8MQ)
- Google Cheza (Qualcomm SDM845)
- Qualcomm Dragonboard 845c (Qualcomm SDM845)
- Hugsun X99 TV Box (Rockchip RK3399)
- Khadas Edge/Edge-V/Captain (Rockchip RK3399)
Updated / expanded boards and platforms:
- Renesas r7s9210 has a lot of new peripherals added
- Polish and fixes for Rockchip-based Chromebooks
- Amlogic G12A has a lot of peripherals added
- Nvidia Jetson Nano sees various fixes and improvements, and is now at
feature parity with TX1

The system counter (sys_ctr) is a programmable system counter
which provides a shared time base to the Cortex A15, A7, A53 etc cores.
It is intended for use in applications where the counter is always
powered on and supports multiple, unrelated clocks. The sys_ctr hardware
supports:
- 56-bit counter width (roll-over time greater than 40 years)
- compare frame(64-bit compare value) contains programmable interrupt
generation when compare value <= counter value.
