|
|
|
The wl1271 chip can be connected via SPI or via SDIO. This
|
|
document describes the binding for the SPI connected chip.
|
|
|
|
Required properties:
|
|
- compatible : Should be "ti,wl1271"
|
|
- reg : Chip select address of device
|
|
- spi-max-frequency : Maximum SPI clocking speed of device in Hz
|
|
- ref-clock-frequency : Reference clock frequency
|
|
- interrupt-parent, interrupts :
|
|
Should contain parameters for 1 interrupt line.
|
|
Interrupt parameters: parent, line number, type.
|
|
- vwlan-supply : Point the node of the regulator that powers/enable the wl1271 chip
|
|
|
|
Optional properties:
|
|
- clock-xtal : boolean, clock is generated from XTAL
|
|
|
|
- Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
|
|
for optional SPI connection related properties,
|
|
|
|
Examples:
|
|
|
|
&spi1 {
|
|
wl1271@1 {
|
|
compatible = "ti,wl1271";
|
|
|
|
reg = <1>;
|
|
spi-max-frequency = <48000000>;
|
|
clock-xtal;
|
|
ref-clock-frequency = <38400000>;
|
|
interrupt-parent = <&gpio3>;
|
|
interrupts = <8 IRQ_TYPE_LEVEL_HIGH>;
|
|
vwlan-supply = <&vwlan_fixed>;
|
|
};
|
|
};
