The example for the CrOS EC PWM is incomplete and now generates a dtc
warning:
Documentation/devicetree/bindings/pwm/google,cros-ec-pwm.example.dts:17.11-23.11:
Warning (unit_address_vs_reg): /example-0/cros-ec@0: node has a unit name, but no reg or ranges property
Fixing this results in more warnings as a parent spi node is needed as
well.

various Spreadtrum SoCs, this series of changes brings a slew of, mostly
minor, fixes and cleanups for existing drivers, as well as some
enhancements to the core code.
Lastly, Uwe is added to the PWM subsystem entry of the MAINTAINERS file,

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
