There was an attempt to fix this in commit +65e6b5f1b4a7 ("MLK-14536: ASoC: wm8960: Fix playback in CPU DAI master mode") +but this broke codec-master mode, thus the patch was partially reverted in +96f0d36e420 ("MLK-14798: arm: dts: imx6ul: Fix wm8960 codec master mode") + +So, remove S20_3LE support for SAI master mode. Clients using this +feature should use codec master mode, which is the default one in the +dts anyway. + +Signed-off-by: Daniel Baluta <daniel.baluta@nxp.com> +--- + sound/soc/fsl/fsl_sai.h | 1 - + 1 file changed, 1 deletion(-) + +--- a/sound/soc/fsl/fsl_sai.h ++++ b/sound/soc/fsl/fsl_sai.h +@@ -10,7 +10,6 @@ + #include <sound/dmaengine_pcm.h> + + #define FSL_SAI_FORMATS (SNDRV_PCM_FMTBIT_S16_LE |\ +- SNDRV_PCM_FMTBIT_S20_3LE |\ + SNDRV_PCM_FMTBIT_S24_LE |\ + SNDRV_PCM_FMTBIT_S32_LE) + |
