| description: | |
| This documents the binding structure and common properties for serial |
| attached TI Bluetooth devices. The following chips are included in this |
| binding: |
| |
| * TI CC256x Bluetooth devices |
| * TI WiLink 7/8 (wl12xx/wl18xx) Shared Transport BT/FM/GPS devices |
| |
| TI WiLink devices have a UART interface for providing Bluetooth, FM radio, |
| and GPS over what's called "shared transport". The shared transport is |
| standard BT HCI protocol with additional channels for the other functions. |
| |
| TI WiLink devices also have a separate WiFi interface as described in |
| wireless/ti,wlcore.yaml. |
| |
| This bindings follows the UART slave device binding in ../serial/serial.yaml. |
