| 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. |
