[PATCH] alsa/usb-audio: Generic DSD detection for Thesycon-based implementations

From: Yue Wang
Date: Mon Jul 23 2018 - 04:53:34 EST


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.
