Subject[PATCH] alsa/usb-audio: Topping DX7s quirk for DSD interface
Date
This patch adds the support for native DSD for Topping DX7s DAC. The
product description is on
http://en.tpdz.net/products_detail/productId=32.html and it's
available on https://www.amazon.com/Balanced-Headphone-Amplifier-Topping-2ES9038Q2M/dp/B07B4VFS21

The DAC uses XMOS chip but uses a special vendor id and product id.
The patch will enable the SNDRV_PCM_FMTBIT_DSD_U32_BE bit for the DAC
hence enable native DSD playback up to DSD512 format.
