| 12 | description: |
| 13 | MT7921S is an SDIO-attached dual-radio WiFi+Bluetooth Combo chip; each |
| 14 | function is its own SDIO function on a shared SDIO interface. The chip |
| 15 | has two dedicated reset lines, one for each function core. |
| 16 | This binding only covers the Bluetooth SDIO function, with one device |
| 17 | node describing only this SDIO function. |
