Reduces the need to add more properties. Great, thanks for letting me know! Will remove it in v2. I see the code in sound/soc/soc-usb.c is still parsing 'usb-soc-be', is that now kept for other use cases or should that be removed as well?

The property usb-soc-be is used by the new SoC USB layer which is used for USB audio offloading on Qualcomm SoCs.
