* Texas Instruments wl12xx/wl18xx wireless lan controller
|
|
The wl12xx/wl18xx chips can be connected via SPI or via SDIO. This
|
document describes the binding for the SPI connected chip.
|
|
Required properties:
|
- compatible : Should be one of the following:
|
* "ti,wl1271"
|
* "ti,wl1273"
|
* "ti,wl1281"
|
* "ti,wl1283"
|
* "ti,wl1801"
|
* "ti,wl1805"
|
* "ti,wl1807"
|
* "ti,wl1831"
|
* "ti,wl1835"
|
* "ti,wl1837"
|
- reg : Chip select address of device
|
- spi-max-frequency : Maximum SPI clocking speed of device in Hz
|
- interrupts : Should contain parameters for 1 interrupt line.
|
- vwlan-supply : Point the node of the regulator that powers/enable the
|
wl12xx/wl18xx chip
|
|
Optional properties:
|
- ref-clock-frequency : Reference clock frequency (should be set for wl12xx)
|
- clock-xtal : boolean, clock is generated from XTAL
|
|
- Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
|
for optional SPI connection related properties,
|
|
Examples:
|
|
For wl12xx family:
|
&spi1 {
|
wlcore: wlcore@1 {
|
compatible = "ti,wl1271";
|
reg = <1>;
|
spi-max-frequency = <48000000>;
|
interrupt-parent = <&gpio3>;
|
interrupts = <8 IRQ_TYPE_LEVEL_HIGH>;
|
vwlan-supply = <&vwlan_fixed>;
|
clock-xtal;
|
ref-clock-frequency = <38400000>;
|
};
|
};
|
|
For wl18xx family:
|
&spi0 {
|
wlcore: wlcore@0 {
|
compatible = "ti,wl1835";
|
reg = <0>;
|
spi-max-frequency = <48000000>;
|
interrupt-parent = <&gpio0>;
|
interrupts = <27 IRQ_TYPE_EDGE_RISING>;
|
vwlan-supply = <&vwlan_fixed>;
|
};
|
};
