Thesycon provides solutions to XMOS chips, and has its own device vendor id.
In this patch, we use generic method to detect DSD capability of Thesycon-based UAC2
implementations in order to support a wide range of current and future devices.
The patch will enable the SNDRV_PCM_FMTBIT_DSD_U32_BE bit for the DAC
hence enable native DSD playback up to DSD512 format.

Heh, don't worry. BTW, at the next submission, please fix the subject
prefix as well. The usual subject line for ALSA code is like:
ALSA: usb-audio: Blah blah...
thanks,
Takashi

Thesycon provides solutions to XMOS chips, and has its own device vendor id.
In this patch, we use generic method to detect DSD capability of Thesycon-based UAC2
implementations in order to support a wide range of current and future devices.
The patch will enable the SNDRV_PCM_FMTBIT_DSD_U32_BE bit for the DAC
hence enable native DSD playback up to DSD512 format.
