+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.
