Because we need to support the multiple codecs (MAX98357A/RT5514/DA7219) on the RK3399 GRU boards, this patch can help us to support these codecs.
Signed-off-by: Xing Zheng zhengxing@rock-chips.com
Changes in v5:
- fix the build warning for missing I2C/CLKDEV_LOOKUP dependency
Changes in v4:
- the compatible name needs to be based on a single reference design, and the name of the board is called "GRU"
- use one i2sX card "rockchip,cpu = <&i2s0>" instead of array that is based on GRU
- rename DOC to rockchip,rk3399-gru-sound.txt
- rename compatible to rockchip,rk3399-gru-sound
- rename source code to rk3399_gru_sound.c
Changes in v3:
- rename DOC to rockchip,rk3399-max98357a-rt5514-da7219.txt
- rename compatible to rockchip,rk3399-max98357a-rt5514-da7219
- rename source code to rk3399_max98357a_rt5514_da7219.c
Changes in v2:
- use the FS 256 to set mclks of the max98357a and rt5514 danamically
- add more sample rate for da7219

These seem fairly standard though a variety of versions in the bindings. Can we use audio-codec and audio-cpu (or cpu or audio-dai) here? Mark?
