Re: [alsa-devel] [PATCH v3] ASoC: rockchip: Add machine driver for MAX98357A/RT5514/DA7219

Hi, Could any guys help me to review this patch?

Thanks.

There are multi codec devices on the RK3399 platform, we can use this patch support and control these codecs.

Signed-off-by: Xing Zhengzhengxing@rock-chips.com

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
