[PATCH 6/7] ARM: dts: Add dts for Raspberry Pi 4 + Cirrus Logic Lochnagar2
Richard Fitzgerald
rf at opensource.cirrus.com
Wed Oct 14 16:54:17 CEST 2020
This is based on the default bcm2711-rpi-4-b.dts.
Configurations are provided for Cirrus Logic codecs CS42L92, CS47L15,
CS47L24, CS47L35, CS47L90 and WM8998.
For each codec there is a sound node and a codec device node and both
default to disabled. Enable the pair for the codec in use.
