| Subject: ASoC: wm8741: Fix setting interface format for DSP modes |
| |
| From: Axel Lin <axel.lin@gmail.com> |
| |
| commit 3a340104fad6ecbea5ad6792a2ea855f0507a6e0 upstream. |
| |
| According to the datasheet: |
| Format Control (05h) |
| BITS[3:2] |
| FMT[1:0] Audio data format selection |
| 00 = right justified mode |
| 01 = left justified mode |
| 10 = I2S mode |
| 11 = DSP mode |
| BIT[4] LRP Polarity selec for LRCLK/DSP mode select |
| 0 = normal LRCLK poalrity/DSP mode A |
| 1 = inverted LRCLK poarity/DSP mode B |
| |
| For SND_SOC_DAIFMT_DSP_A, we should set 0x000C instead of 0x0003. |
| For SND_SOC_DAIFMT_DSP_B, we should set 0x001C instead of 0x0013. |
