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.
