1* Texas Instruments wl1251 wireless lan controller 2 3The wl1251 chip can be connected via SPI or via SDIO. This 4document describes the binding for the SPI connected chip. 5 6Required properties: 7- compatible : Should be "ti,wl1251" 8- reg : Chip select address of device 9- spi-max-frequency : Maximum SPI clocking speed of device in Hz 10- interrupts : Should contain interrupt line 11- vio-supply : phandle to regulator providing VIO 12- ti,power-gpio : GPIO connected to chip's PMEN pin 13 14Optional properties: 15- ti,wl1251-has-eeprom : boolean, the wl1251 has an eeprom connected, which 16 provides configuration data (calibration, MAC, ...) 17- Please consult Documentation/devicetree/bindings/spi/spi-bus.txt 18 for optional SPI connection related properties, 19 20Examples: 21 22&spi1 { 23 wl1251@0 { 24 compatible = "ti,wl1251"; 25 26 reg = <0>; 27 spi-max-frequency = <48000000>; 28 spi-cpol; 29 spi-cpha; 30 31 interrupt-parent = <&gpio2>; 32 interrupts = <10 IRQ_TYPE_NONE>; /* gpio line 42 */ 33 34 vio-supply = <&vio>; 35 ti,power-gpio = <&gpio3 23 GPIO_ACTIVE_HIGH>; /* 87 */ 36 }; 37}; 38
