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.



These devices also have a separate WiFi interface as described in

wireless/ti,wlcore.txt.



This bindings follows the UART slave device binding in

../serial/slave-device.txt.



Required properties:

 - compatible: should be one of the following:

    "ti,wl1271-st"

    "ti,wl1273-st"

    "ti,wl1831-st"

    "ti,wl1835-st"

    "ti,wl1837-st"



Optional properties:

 - enable-gpios : GPIO signal controlling enabling of BT. Active high.

 - vio-supply : Vio input supply (1.8V)

 - vbat-supply : Vbat input supply (2.9-4.8V)



Example:



&serial0 {

	compatible = "ns16550a";

	...

	bluetooth {

		compatible = "ti,wl1835-st";

		enable-gpios = <&gpio1 7 GPIO_ACTIVE_HIGH>;

	};

};
