ALSA: pcm: add new DSD sampleformat for native DSD playback on XMOS based devices
XMOS based USB DACs with native DSD support expose this feature via a USB alternate setting. The audio format is either 32-bit raw or a 32-bit PCM format. To utilize this feature on linux this patch introduces a new 32-bit DSD sampleformat DSD_U32_LE. A follow up patch will add a quirk for XMOS based devices to utilize the new format. Further patches will add support to alsa-lib. Signed-off-by: Jurgen Kramer <gtmkramer@xs4all.nl> Signed-off-by: Takashi Iwai <tiwai@suse.de>
