78dcad6daa dt-bindings: pwm: Correct indentation and style in DTS example
DTS example in the bindings should be indented with 2- or 4-spaces and
aligned with opening '- |', so correct any differences like 3-spaces or
mixtures 2- and 4-spaces in one binding.

No functional changes here, but saves some comments during reviews of
new patches built on existing code.

32207e9ddf dt-bindings: pwm: describe the cells in #pwm-cells in pwm.yaml
When commit 89650a1e3b ("dt-bindings: pwm: Convert PWM bindings
to json-schema") converted the pwm provider section of the text binding
to dt-schema it also updated all references to pwm.txt in pwm provider
bindings to pwm.yaml.

Most pwm provider bindings had a reference to pwm.txt as it contains a
description of what the cells in #pwm-cells are, albeit in the consumer
section of the document. Only information in the provider section of the
document was moved to the yaml binding, and it contains no information
about the cell format, making all references to it for the cell format
unhelpful.

Pull more ARM SoC updates from Arnd Bergmann:
 "These are changes that for some reason ended up not making it into the

   - A rework of the omap clock support that touches both drivers and
     device tree files

   - The reset controller branch changes that had a dependency on late

5fd61cc281 dt-bindings: pwm: amlogic: Add a new binding for meson8 pwm types
The binding that is used up to now describe which input the PWM
channel multiplexer should pick among its possible parents,
which are hardcoded in the driver. This isn't a good binding in
the sense that it should describe hardware but not usage.

Add a new binding deprecating the old one that uses clocks in a
better way and how clocks are usually used today: The list of
clocks describe the inputs of the PWM block as they are realised
in hardware.

So deprecate the old bindings and introduce a compatible per SoC
family to replace these.

c2dd6b93f6 dt-bindings: pwm: amlogic: fix s4 bindings
s4 has been added to the compatible list while converting the Amlogic PWM
binding documentation from txt to yaml.

However, on the s4, the clock bindings have different meaning compared to
the previous SoCs.

On the previous SoCs the clock bindings used to describe which input the
PWM channel multiplexer should pick among its possible parents.

This is very much tied to the driver implementation, instead of describing
the HW for what it is. When support for the Amlogic PWM was first added,
how to deal with clocks through DT was not as clear as it nowadays.
The Linux driver now ignores this DT setting, but still relies on the
hard-coded list of clock sources.

On the s4, the input multiplexer is gone. The clock bindings actually
describe the clock as it exists, not a setting. The property has a
different meaning, even if it is still 2 clocks and it would pass the check
when support is actually added.

Also the s4 cannot work if the clocks are not provided, so the property is
no longer optional.

Finally, for once it makes sense to see the input as being numbered
somehow. No need to bother with clock-names on the s4 type of PWM.

Pull SoC DT updates from Arnd Bergmann:
 "There is one new SoC for each 32-bit Arm and 64-bit RISC-V, but both
  the Rockchips rv1109 and Sopgho CV1812H are just minor variations of
  already supported chips.

  The other six new SoCs are all part of existing arm64 families, but
  are somewhat more interesting:

   - Samsung ExynosAutov920 is an automotive chip, and the first one we
     support based on the Cortex-A78AE core with lockstep mode.

   - Google gs101 (Tensor G1) is the chip used in a number of Pixel
     phones, and is grouped with Samsung Exynos here since it is based
     on the same SoC design, sharing most of its IP blocks with that
     series.

   - MediaTek MT8188 is a new chip used for mid-range tablets and
     Chromebooks, using two Cortex-A78 cores where the older MT8195 had
     four of them.

   - Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range
     phone SoC and the first supported chip based on Cortex-X4,
     Cortex-A720 and Cortex-A520.

   - Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest Laptop
     chip using the custom Oryon cores.

   - Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on
     Cortex-A76 and Cortex-A55

  In terms of boards, we have

   - Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto
     G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs.

   - Multiple Rockchips mobile gaming systems (Anbernic RG351V, Powkiddy
     RK2023, Powkiddy X55) along with the Sonoff iHost Smart Home Hub
     and a few Rockchips SBCs

   - Some ComXpress boards based on Marvell CN913x, which is the
     follow-up to Armada 7xxx/8xxx.

   - Six new industrial/embedded boards based on NXP i.MX8 and i.MX9

   - Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer.

   - Toradex Verdin AM62 Mallow carrier for TI AM62

   - Huashan Pi board based on the SophGo CV1812H RISC-V chip

   - Two boards based on Allwinner H616/H618

   - A number of reference boards for various added SoCs from Qualcomm,
     Mediatek, Google, Samsung, NXP and Spreadtrum

  As usual, there are cleanups and warning fixes across all platforms as
  well as added features for several of them"
