As indicated in

developers copying it into new .yaml files, and being asked to remove
it.

8eca6b0a64 pwm: Changes for v5.19-rc1
Quite a large number of conversions this time around, courtesy of Uwe
 who has been working tirelessly on these. No drivers of the legacy API
 are left at this point, so as a next step the old API can be removed.
 
 Support is added for a few new devices such as the Xilinx AXI timer-
 based PWMs and the PWM IP found on Sunplus SoCs.
 
 Other than that, there's a number of fixes, cleanups and optimizations.

82b9a6bb4b dt-bindings: timer: Update TI timer to yaml
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We also correct the issue with the old binding that was out of date for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.

Merge tag 'riscv-for-linus-5.18-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux

Pull RISC-V updates from Palmer Dabbelt:

 - Support for Sv57-based virtual memory.

 - Various improvements for the MicroChip PolarFire SOC and the
   associated Icicle dev board, which should allow upstream kernels to
   boot without any additional modifications.

 - An improved memmove() implementation.

 - Support for the new Ssconfpmf and SBI PMU extensions, which allows
   for a much more useful perf implementation on RISC-V systems.

 - Support for restartable sequences.

Currently any node whose name starts with the "pwm-" prefix will match
this schema and in turn required the "#pwm-cells" property. Avoid this
by marking the schema with select: false, therefore only activating the
schema when directly included from a PWM controller schema file.

e083bbd604 ARM: Devicetree material for 5.14
Like always, the DT branch is sizable. There are numerous additions and

 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
  - Qualcomm: lots of additions for peripherals across several SoCs, and
    new support for Microsoft Surface Duo (SM8150-based), Huawei Ascend G7.
  - i.MX: Numerous additions of features across SoCs and boards.
  - Allwinner: More device bindings for V3s, Forlinx OKA40i-C and NanoPi

8c1bfd7460 pwm: Changes for v5.14-rc1
This contains mostly various fixes, cleanups and some conversions to the
 atomic API. One noteworthy change is that PWM consumers can now pass a
 hint to the PWM core about the PWM usage, enabling PWM providers to
 implement various optimizations.
 
 There's also a fair bit of simplification here with the addition of some
 device-managed helpers as well as unification between the DT and ACPI
 firmware interfaces.

9939648a53 dt-bindings: pwm: pwm-tiecap: Add compatible string for AM64 SoC
Add compatible string for AM64 SoC in device tree binding.
IP is compatible with ti,am3352-ecap, so adding the AM64 compatible
under enum of one of the compatible list entry.
