imx8m mini yocto 4.14.98默认的是wm8524,我这里使用的是wm8978音频驱动,接口是imx8上的sai3。

我该如何配置设备树让它工作?我发现驱动在kernel-source/sound/soc/codecs/wm8978.c里,但是kernel-source/sound/soc/fsl/下没有imx-wm8978.c 我该如何去修改imx-wm8524.c?有人修改过吗?希望能帮助我谢谢!

Hi jianfei 

for software modifications one can reuse imx-wm8524.c, taking differencies

from wm8978 datasheet. Use Porting Guide included in Linux 4.19.35_1.1.0 Documentation

and sect.7.1 Advanced Linux Sound Architecture (ALSA) System on a
Chip (ASoC) Sound Linux Manual.

Best regards
igor
