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,wl1281-st"
|
|
"ti,wl1283-st"
|
|
"ti,wl1285-st"
|
|
"ti,wl1801-st"
|
|
"ti,wl1805-st"
|
|
"ti,wl1807-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)
|
|
- clocks : Must contain an entry, for each entry in clock-names.
|
|
See ../clocks/clock-bindings.txt for details.
|
|
- clock-names : Must include the following entry:
|
|
"ext_clock" (External clock provided to the TI combo chip).
|
|
|
|
Example:
|
|
|
|
&serial0 {
|
|
compatible = "ns16550a";
|
|
...
|
|
bluetooth {
|
|
compatible = "ti,wl1835-st";
|
|
enable-gpios = <&gpio1 7 GPIO_ACTIVE_HIGH>;
|
|
clocks = <&clk32k_wl18xx>;
|
|
clock-names = "ext_clock";
|
|
};
|
|
};
