* Texas Instruments wl1251 wireless lan controller
The wl1251 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,wl1251"
- reg : Chip select address of device
- spi-max-frequency : Maximum SPI clocking speed of device in Hz
- interrupts : Should contain interrupt line
- interrupt-parent : Should be the phandle for the interrupt controller
that services interrupts for this device
- vio-supply : phandle to regulator providing VIO
- ti,power-gpio : GPIO connected to chip's PMEN pin
Optional properties:
- ti,wl1251-has-eeprom : boolean, the wl1251 has an eeprom connected, which
provides configuration data (calibration, MAC, ...)
- Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
for optional SPI connection related properties,
Examples:
&spi1 {
wl1251@0 {
compatible = "ti,wl1251";
reg = <0>;
spi-max-frequency = <48000000>;
spi-cpol;
spi-cpha;
interrupt-parent = <&gpio2>;
interrupts = <10 IRQ_TYPE_NONE>; /* gpio line 42 */
vio-supply = <&vio>;
ti,power-gpio = <&gpio3 23 GPIO_ACTIVE_HIGH>; /* 87 */
};
};
