Hi Takashi

My apologies, it's my first time sending a patch to the kernel, so there're quite a few things I need to improve.

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/B0...

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.

Thanks again.

Please give more explanation. No commit message already indicates that something is very wrong, no matter what the change is.

thanks,
