Subject: [PATCH 1/2] arm64: dts: rockchip: fix audio-supply for Rock Pi 4
Date: Wed, 27 Oct 2021 16:37:25 +0200	[thread overview]
Message-ID: <20211027143726.165809-1-knaerzche@gmail.com> (raw)

As stated in the schematics [1] and [2] P5 the APIO5 domain is supplied
by RK808-D Buck4, which in our case vcc1v8_codec - i.e. a 1.8 V regulator.

Currently only white noise comes from the ES8316's output, which - for
whatever reason - came up only after the the correct switch from i2s0_8ch_bus
to i2s0_2ch_bus for i2s0's pinctrl was done.

Fix this by setting the correct regulator for audio-supply.
