Subject: [PATCH] ALSA: usb-audio: Generic DSD detection for Thesycon-based implementations
Git-commit: 1ea0358ecb848058b35b6da13d7f4c08610a73a8
Patch-mainline: v4.19-rc1
References: bsc#1121278
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.
