[PATCH 3/4] arm64: dts: mediatek: cherry: Add external codecs and speaker amplifier

From: AngeloGioacchino Del Regno
Date: Thu Sep 22 2022 - 05:49:38 EST


The entire Cherry family has two digital microphones, for which
we use the generic dmic-codec, linked to the MT6359 PMIC.
Moreover, it uses a Realtek RT1019p amplifier for the speakers
and has either a Realtek RT5682i or RT5682s audio codec on I2C2:
specifically, RT5682i is found on Tomato's rev 1 and rev 2 boards,
while RT5682s is found in rev3 and rev4 boards.
