+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.
