ROCKCHIP with MAX98357A/RT5514/DA7219 codecs on GRU boards
Required properties:
- compatible: "rockchip,rk3399-gru-sound"
- rockchip,cpu: The phandle of the Rockchip I2S controller that's
connected to the codecs
- rockchip,codec: The phandle of the audio codecs
Optional properties:
- dmic-wakeup-delay-ms : specify delay time (ms) for DMIC ready.
If this option is specified, which means it's required dmic need

rockchip,cpu = <&i2s0>;
rockchip,codec = <&max98357a &rt5514 &da7219>;
