Revert commit 51284d8b1dbc ("dt-bindings: mfd: syscon: Document the

reality and clearly incorrect in respect of renesas,r9a08g046-lvds-cmn.
It wasn't ever build-tested by author on their DTS, either.
The documented renesas,r9a08g046-lvds-cmn compatible clearly disallows
any children and simple-mfd fallback, however its only use in original
patchset is with simple-mfd and children, so this could have never
worked.

The st,stmpe-pwm binding is already covered by the MFD schema in
Documentation/devicetree/bindings/mfd/st,stmpe.yaml. However, the
PWM subnode was missing a 'required' properties block. This allowed
Device Tree nodes to pass validation even if the 'compatible'
string was omitted. This omission could lead to probe failures
at runtime.
Fix the schema by adding the missing 'required' block.

AST2700 consists of two interconnected SoC instances, each with its own
System Control Unit (SCU). The SCU0 provides pin control, interrupt
controllers, clocks, resets, and address-space mappings for the
Secondary and Tertiary Service Processors (SSP and TSP).
Describe the SSP/TSP address mappings using the standard
memory-region and memory-region-names properties.
Disallow legacy child nodes that are not present on AST2700, including
p2a-control and smp-memram. The latter is unnecessary as software can
access the scratch registers via the SCU syscon.
Also allow the AST2700 SoC0 pin controller to be described as a child
node of the SCU0, and add an example illustrating the SCU0 layout,
including reserved-memory, interrupt controllers, and pinctrl.

Apple Silicon devices integrate a vast array of sensors, monitoring
current, power, temperature, and voltage across almost every part of
the system. The sensors themselves are all connected to the System
Management Controller (SMC). The SMC firmware exposes the data
reported by these sensors via its standard FourCC-based key-value
API. The SMC is also responsible for monitoring and controlling any
fans connected to the system, exposing them in the same way.
For reasons known only to Apple, each device exposes its sensors with
an almost totally unique set of keys. This is true even for devices
which share an SoC. An M1 Mac mini, for example, will report its core
temperatures on different keys to an M1 MacBook Pro. Worse still, the
SMC does not provide a way to enumerate the available keys at runtime,
nor do the keys follow any sort of reasonable or consistent naming
rules that could be used to deduce their purpose. We must therefore
know which keys are present on any given device, and which function
they serve, ahead of time.
Add a schema so that we can describe the available sensors for a given
Apple Silicon device in the Devicetree.

of effort from Brian Masney. Now the only option is to use determine_rate(),
which is good because that takes a struct argument instead of just a couple
unsigned longs, allowing us to easily modify the way we determine and set rates
in the clk tree.
Beyond that core framework change we've got the typical pile of new SoC clk
driver additions, fixes for clk data and/or adding missing clks because the
consumer driver using those clks wasn't ready, etc. The usual suspects are all
here: Qualcomm, Samsung, Mediatek, and Rockchip along with some newcomers
making RISC-V SoCs like ESWIN's eic700 and Tenstorrent's Atlantis. The clk
driver side of this looks pretty normal.

- ESWIN eic700 SoC clk support
- Econet EN751221 SoC clock/reset support
- Global TCSR, RPMh, and display clock controller support for
the Qualcomm Eliza platform
- TCSR, the multiple global, and the RPMh clock controller

Lots of little things in here, nothing major, just constant
improvements, updates, and new features. Highlights are:
- new USB power supply driver support (will cause merge conflicts in
drivers/power/supply/Makefile, but it's a simple fix) These changes
did touch outside of drivers/usb/ but got acks from the relevant
mantainers for them.
- dts file updates and conversions
- string function conversions into "safer" ones
- new device quirks
- xhci driver updates
- usb gadget driver minor fixes
- typec driver additions and updates
- small number of thunderbolt driver changes
- dwc3 driver updates and additions of new hardware support

The ROHM BD79300 is almost identical to the BD72720. Main differences
are the initial values for some of the registers. Thus, it appears the
BD79300 can be handled with same software as BD72720.
Adding the compatible for the BD79300 enables people to use the real IC
type in the device-tree instead of claiming it is BD72720. This does
also help differentiating the ICs if appears it is needed.
Add own compatible for the BD73900 and mark BD72720 as a fall-back.

following PMICs: PMK8550, PM8550, PM8550B and PM8550VX PMICs.
It is similar to PMIC5-Gen2, with SW communication to ADCs on all PMICs
going through PBS(Programmable Boot Sequence) firmware through a single
register interface. This interface is implemented on SDAM (Shared
Direct Access Memory) peripherals on the master PMIC PMK8550 rather
than a dedicated ADC peripheral.

Merge series from André Draszik <andre.draszik@linaro.org>:
This series extends the existing S2MPG10 PMIC driver to add support for
the regulators, and adds new S2MPG11 core and regulator drivers.
The patches are kept together in one series, due to S2MPG11 and its
regulators being very similar to S2MPG10.
The Samsung S2MPG11 PMIC is a Power Management IC for mobile
applications with buck converters, various LDOs, power meters, and
additional GPIO interfaces. It typically complements an S2MPG10 PMIC in
a main/sub configuration as the sub-PMIC and both are used on the
Google Pixel 6 and 6 Pro (oriole / raven).
A DT update for Oriole / Raven to enable these is required which I will
send out separately.
The simple audio codec bindings were consolidated into
trivial-codec.yaml by commit 4acbfcf11c ("ASoC: dt-bindings:
consolidate simple audio codec to trivial-codec.yaml").
Update the DA9055 binding documentation to reference the new
trivial-codec.yaml location.

The Samsung S2MPG11 PMIC is similar to the existing S2MPG10 PMIC
supported by this binding, but still differs enough from it to justify
a separate binding.
It is a Power Management IC for mobile applications with buck
converters, various LDOs, power meters, NTC thermistor inputs, and
additional GPIO interfaces and typically complements an S2MPG10 PMIC in
a main/sub configuration as the sub-PMIC.
Like S2MPG10, communication is via the Samsung ACPM firmware and it
therefore needs to be a child of the ACPM firmware node.
Add the PMIC, the regulators node, and the supply inputs of the
regulator rails, with the supply names matching the datasheet.
Note: S2MPG11 is typically used as the sub-PMIC together with an
S2MPG10 PMIC in a main/sub configuration, hence the datasheet and the
binding both suffix the supplies with an 's'.

The samsung,s2mpg10-pmic binding is going to acquire various additional
properties. To avoid making the common samsung,s2mps11 binding file too
complicated due to additional nesting, split s2mpg10 out into its own

As a side-effect, the oneOf for the interrupts is not required anymore,
as the required: node is at the top-level now.

The Realtek system controllers are already in use with only generic
'"syscon", "simple-mfd"' compatibles and are missing specific
compatibles as required. Add a schema with specific compatibles. The
labels used in .dts files serve as the basis for the names.
It's doubtful the child nodes upstream are complete and I don't have
documentation, so the specific child nodes aren't documented here. Of
the ones in use, bindings already exist for them.
