[alsa-devel] [PATCH] ASoC: fsl_asrc: add protection for the asrc of older version
by S.j. Wang 01 Mar '19

01 Mar '19

There is a constraint for the channel number setting on the asrc of older version (e.g. imx35), the channel number should be even, odd number isn't valid. So add protection when the asrc of older version is used.

If so, then maybe SNDRV_PCM_FMTBIT_S32_LE should > stay. Yes, the S32_LE can be accepted by device, it seems like that the device only Use the upper 24bit, so the S32_LE result is same as S24_LE, do you think the S32_LE should be remained?
