[alsa-devel] [PATCH v3 1/2] ALSA: pcm: add SNDRV_PCM_FORMAT_{S, U}20
This format is similar to existing SNDRV_PCM_FORMAT_{S,U}20_3 that keep 20-bit PCM samples in 3 bytes, however i.MX6 platform SSI FIFO does not allow 3-byte accesses (including DMA) so a 4-byte (more conventional) format is needed for it.
Signed-off-by: Maciej S. Szmigiero mail@maciej.szmigiero.name --- Changes from v1: Drop "_4" suffix from these formats since they aren't non-standard ones, use empty format slots starting from format number 25 for them, add information that they are LSB justified formats.
Changes from v2: Adapt a comment in sound/core/pcm_misc.c so it still refers to the same sample formats as before.
Corresponding alsa-lib changes will be posted as soon as this patch is merged on the kernel side, to keep alsa-lib and kernel synchronized.

In next time to post any of your v2 patchset, it's better to add commenters of v1 patchset to CC list, so that your patch reaches the person who has practical interests in it.
I'm waiting for your another patch to alsa-lib.
Thanks

This define is used as a template of supported formats only in ASoC AC'97 CODECs. A list of effective supported sample formats will be calculated as an intersection of CODEC and CPU-supported formats (and DMA controller-supported bit widths).
This means that as long as ASoC CPUs don't add these sample formats to their list of supported formats they should not be offered as supported by any sound card.
Also, we already have similar SNDRV_PCM_FMTBIT_S20_3 formats in this define.
