Subject: [PATCH 0/2] Add PWM support for Meson8
Date: Wed, 12 Jul 2017 00:20:13 +0200	[thread overview]
Message-ID: <20170711222015.10401-1-martin.blumenstingl@googlemail.com> (raw)

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.

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
