Subject: [PATCH 0/5] dts: amlogic: switch to the new PWM controller binding

This series switches all Amlogic SoCs to use the new PWM controller
binding. The main benefits of the new binding are:
- the pwm controller driver now picks the best possible clock to
  achieve the most accurate pwm output
- board.dts don't have to know about the pwm clock inputs anymore (as
  the driver picks the best one automatically)
- new SoCs only need a new compatible string but no pwm-meson driver
  changes, assuming only the clock inputs differ from older IP
  revisions

This silences the following warning(s) at boot (for each pwm
controller instance):
  using obsolete compatible, please consider updating dt

I have tested this on two devices:
- meson8b: odroidc1 (boots fine and cycling through all CPU
  frequencies and thus voltages works fine)
- meson-sm1: x96-air-gbit (boots and the rtw8822cs SDIO card is
  detected, so the 32kHz clock for the SDIO card works)

Since I cannot test all devices I'm asking for this series to be
applied so the Kernel CI board farm can help verify it works on all
boards available there.
