Some QE GPIO pins have an associated interrupt line in the QE PIC to
signal state changes on the pin. Add the corresponding
interrupt-controller / nexus properties to the QE GPIO binding.
Because the GPIO controller does not perform any interrupt handling
itself, a nexus node (interrupt-map) is used to map each GPIO line
supporting IRQ to the parent QE PIC interrupt domain.
As the QE PIC can be configured to generate an interrupt on either a
high-to-low transition or any change in signal state, three
interrupt-map entries are needed per GPIO pin that can yield an
interrupt (falling, both, and the "none" case which defaults to both in
QE PIC). This overhead is necessary because the interrupt-map-pass-thru
property is not part of the DT specification.
The interrupt-map property is optional: it is not required for GPIO
banks that have no interrupt capable GPIO line (e.g. port D on MPC8323),
or when interrupt functionality is not used.
Update the example to show a scenario where each bank supports a
different numbers of IRQs, or no IRQs at all.

EIO (Extended IO) GPIO is a Xilinx IP block that exposes
multiplexed I/O pins through an EIO interface.
The EIO GPIO block has 2 banks with 26 GPIOs each (52 total).
The GPIO width cannot be determined from the hardware registers,
the driver relies on the compatible string to select the correct
bank/pin configuration. A new compatible is therefore required.
The block is currently present on xa2ve3288 silicon.
The compatible string uses version 1.0 matching the IP core version.

controller, which controls power supplies to the panel and the touch
screen and provides reset pins for both the panel and the touchscreen.
Also it provides a simple PWM controller for panel backlight.
Add bindings for these GPIO controllers. As overall integration might be
not very obvious (and it differs significantly from the bindings used by
the original drivers), provide complete example with the on-board
regulators and the DSI panel.

The 74HC595 and 74LVC594 shift registers latch their outputs until the
first serial write, so boards that depend on a specific power-on pattern
(for example active-low indicators, reset lines, or other signals that
must come up non-zero) have no way to express that today: the Linux
driver always writes zeros from its zero-initialised buffer during
probe.
Document support for the existing lines-initial-states bitmask, already
defined for nxp,pcf8575, so the same convention covers this output-only
device. Bit N corresponds to GPIO line N. Because the 74HC595/74LVC594
family is push-pull output only (no input mode, no high-impedance state
under software control), bit=0 drives the line low and bit=1 drives it
high; this differs from nxp,pcf8575, where the 0/1 polarity reflects the
quasi-bidirectional nature of that part.
The bitmask covers up to 32 lines, which fits the typical 1-4 chip
cascades that appear in tree. Should longer chains require seeding in
the future, the property can be extended to a uint32-array without
breaking the bit-N-equals-line-N convention.

Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for
controlling pins.
Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.
There's also a number of driver reworks and refactoring, documentation
updates, some bug-fixes and new tests.

Traditionally, firmware will provide a GPIO interface or a pin control
interface. However, the SCMI protocol provides a generic pin control
interface and the GPIO support is built on top of that using the normal
pin control interfaces. Potentially, other firmware will adopt a
similar generic approach in the future.
Document how to configure the GPIO device.

The microchip,mpfs-gpio binding suffered greatly due to being written
with a narrow minded view of the controller, and the interrupt bits
ended up incorrect. It was mistakenly assumed that the interrupt
configuration was set by platform firmware, based on the FPGA
configuration, and that the GPIO DT nodes were the only way to really
communicate interrupt configuration to software.
Instead, the mux should be a device in its own right, and the GPIO
controllers should be connected to it, rather than to the PLIC.
Now that a binding exists for that mux, try to fix the misconceptions
in the GPIO controller binding.
Firstly, it's not possible for this controller to have fewer than 14
GPIOs, and thus 14 interrupts also. There are three controllers, with
14, 24 & 32 GPIOs each. The fabric core, CoreGPIO, can of course have
a customisable number of GPIOs.
The example is wacky too - it follows from the incorrect understanding
that the GPIO controllers are connected to the PLIC directly. They are
not however, with a mux sitting in between. Update the example to use
the mux as a parent, and the interrupt numbers at the mux for GPIO2 as
the example - rather than the strange looking, repeated <53>.

Both CoreGPIO and the hardened versions of it on mpfs and pic64gx have a
reset pin. For the former, usually this is wired to a common fabric
reset not managed by software and for the latter two the platform
firmware takes them out of reset on first-party boards (or those using
modified versions of the vendor firmware), but not all boards may take
this approach. Permit providing a reset in devicetree for Linux, or
other devicetree-consuming software, to use.

Extend the existing Tegra186 GPIO controller device tree bindings with
support for the GPIO controller found on Tegra264. The number of pins
is slightly different, but the programming model remains the same.
Add a new header, include/dt-bindings/gpio/nvidia,tegra264-gpio.h,
that defines port IDs as well as the TEGRA264_MAIN_GPIO() helper,
both of which are used in conjunction to create a unique specifier
for each pin.
On Tegra, GPIO wake events are latched and routed via the PMC.
Document the standard DT property, wakeup-parent, which is a phandle to
the PMC interrupt controller that provides the parent wake interrupt
domain for the GPIO controller. If the property is absent the driver
falls back to a compatible-based lookup.

In commit f48b5e8bc2 ("dt-bindings: gpio-mmio: Add compatible string
for opencores,gpio") we marked opencores,gpio to be allowed with
brcm,bcm6345-gpio. This was wrong, opencores,gpio is not compatible with
brcm,bcm6345-gpio. It has a different register map and is 8-bit vs
Broadcom which is 32-bit. Change opencores,gpio to be a separate
compatible string for MMIO GPIO.
Also, as this change rewrote the entire enum, I took this opportunity to
alphabetically sort the list.

DT core:
- Add of_machine_device_match() and of_machine_get_match_data()
helpers and convert users treewide
- Fix bounds checking of address properties in FDT code. Rework the
code to have a single implementation of the bounds checks.

yamllint has gained a new check which checks for inconsistent quoting
(mixed " and ' quotes within a file). Fix all the cases yamllint found
so we can enable the check (once the check is in a release). As single
quotes are (slightly) preferred, use them throughout the modified files
even if double quotes are mostly used.

Add a device tree binding for the QIXIS FPGA based GPIO controller.
Depending on the board, the QIXIS FPGA exposes registers which act as a
GPIO controller, each with 8 GPIO lines of fixed direction.
Since each QIXIS FPGA layout has its particularities, add a separate
compatible string for each board/GPIO register combination supported.
Since these GPIO controllers are trivial, make use of the newly added
trivial-gpio.yaml file instead of creating an entirely new one.

some refactoring. The most notable additions include new drivers for Loongson's Security
Engine, RNG and TPM, new drivers for TI's TPS6594 Power Button and BQ257xx Charger ICs.
The rest of the set provides a return value check fix and a refactoring to use a more modern
GPIO API for the VEXPRESS sysreg driver, the removal of a deprecated IRQ ACK function from the
MC13xxx RTC driver and a new DT binding for the aforementioned TI BQ257xx charger.
New Support & Features
- Add a suite of drivers for the Loongson Security Engine, including the core controller, a
Random Number Generator (RNG) and Trusted Platform Module (TPM) support.
- Introduce support for the TI TPS6594 PMIC's power button, including the input driver, MFD
cell registration, and a system power-off handler.
- Add comprehensive support for the TI BQ257xx series of charger ICs, including the core MFD
driver and a power supply driver for the charger functionality.
Improvements & Fixes
- Check the return value of devm_gpiochip_add_data() in the VEXPRESS sysreg driver to prevent
potential silent failures.
Cleanups & Refactoring
- Add a MAINTAINERS entry for the new Loongson Security Engine drivers.
- Convert the VEXPRESS sysreg driver to use the modern generic GPIO chip API.
Removals
- Remove the deprecated and unused mc13xxx_irq_ack() function from the MC13xxx RTC, input and
touchscreen drivers.
Device Tree Bindings Updates

Move several embedded controller bindings (like ChromeOS EC, Gateworks
System Controller and Kontron sl28cpld Board Management) to new
subdirectory "embedded-controller" matching their purpose.
An embedded controller (EC) is a discrete component that contains a
microcontroller (i.e. a small CPU running a small firmware without
operating system) mounted into a larger computer system running
a fully fledged operating system that needs to utilize the embedded
controller as part of its operation.
So far the EC bindings were split between "mfd" and "platform"
directory. MFD name comes from Linux, not hardware, and "platform" is a
bit too generic.
Rename Gateworks GSC and Huawei Gaokun filenames to match compatible, as
preferred for bindings.

In case the trivial-gpio schema is referenced through a $ref like
/schemas/trivial-gpio.yaml to match its current schema ID, the following
error message is displayed:
Error in referenced schema matching $id: http://devicetree.org/schemas/trivial-gpio.yaml
Tried these paths (check schema $id if path is wrong):
/path/to/linux/Documentation/devicetree/bindings/trivial-gpio.yaml
/path/to/dtchema/schemas/trivial-gpio.yaml
Fix this by adding the 'gpio' folder to the schema's ID to match its
file path.

Loongson-2K0300 ships a GPIO controller whose input/output control logic
is similar to previous generation of SoCs. Additionally, it acts as an
interrupt-controller supporting both level and edge interrupts and has a
distinct reset signal.
Describe its compatible in devicetree. We enlarge the maximum value of
ngpios to 128, since the controller technically supports at most 128
pins, although only 106 are routed out of the package. Properties for
interrupt-controllers and resets are introduced and limited as LS2K0300
only.
