[PATCH v2 0/3] pwm: Add support for Amlogic Meson G12A

[Neil Armstrong]

This adds support for the PWM modules on the Amlogic Meson G12A SoC
family, including bindings changes and DT nodes.

Changes since v1:
- Add two different AO compatible to distinguish the different clock sources

Neil Armstrong (3):
  dt-bindings: pwm: Update bindings for the Meson G12A Family
  pwm: meson: Add clock source configuration for Meson G12A
  arm64: dts: meson-g12a: Add PWM nodes

[PATCH v2 1/3] dt-bindings: pwm: Update bindings for the Meson G12A Family

[Neil Armstrong]

Update the doc to explicitly support Meson G12A Family.
The 2 first (A & B) AO PWM uses different clock source than the last 2
(C & D) AO PWM modules, thus we need to differentiate them.
