Signed-off-by: Shenghao Ding <[email protected]>
---
Changes in v5:
- remove /* __TAS2781_LIB_H__ */ at the end of the file
- remove #include <linux/kernel.h> in the tas2781.h
- remove enum channel in tas2781-dsp.h
- Add TASDEVICE_MAX_CHANNELS in tas2781-dsp.h
- remove global addr related definition in tas2781.h
- reorder the member in tasdevice_priv
- fix the firmware version compatibility issue
