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.

Hi,

0x152a is Thesycon's VID and if it's based on XMOS I'd recommend to try
adding the 0x152a VID to the generic DSD capability auto-detect list
instead of this old device specific list.
I consider it very likely that it would work that way and at the same
time also cover all other devices with the same firmware and Thesycon's VID.
Best regards,

Thanks for the comment Jussi. Let's drop this patch, and I will send a
new patch with this generic approach shortly. The new patch will have
a different commit title and message.
