Cover letter [PATCH 0/2] Add PWM support for Meson8

Quoted 5 lines · Martin Blumenstingl

This series moves the pwm_ab and pwm_cd nodes to the common meson.dtsi. According to Amlogic's GPL kernel sources Meson6 contains the same PWM IP blocks for pwm_ab and pwm_cd (at the same register offsets) as Meson8 and Meson8b.

Quoted 7 lines

pwm_ef on the other hand does not exist on Meson6, so it stays in meson8b.dtsi (and is added to meson8b.dtsi).
Known usages of the PWM controllers:
- controlling the brightness of the system LED
- generating the 32.768kHz wifi LPO clock
- controlling the VDDEE (CPU) voltage

Applied to v4.14/dt,

Thanks,

Kevin
