[PATCH 0/3] arm64: dts: qcom: Add audio support for Nord platform

[Shawn Guo]

This series enables audio playback and capture on the Nord RRD and
Nord Ride SX (nord-ride-embedded) boards.

The first patch adds the GPR node with the APM and PRM services to the
Nord SoC DTSI, which the Q6APM audio stack needs to talk to the ADSP.
The remaining two patches add the board-level pieces: a sound card with
a PCM1681 playback link and an ADAU1979 capture link, both over
Tertiary MI2S, the codec nodes on I2C18, and the TCA6408 I/O expander
whose hogged outputs gate the DAC.
