description:
MT7921S is an SDIO-attached dual-radio WiFi+Bluetooth Combo chip; each
function is its own SDIO function on a shared SDIO interface. The chip
has two dedicated reset lines, one for each function core.
This binding only covers the Bluetooth SDIO function, with one device
node describing only this SDIO function.
