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- interrupt-parent : Should be the phandle for the interrupt controller 12 that services interrupts for this device 13- vio-supply : phandle to regulator providing VIO 14- ti,power-gpio : GPIO connected to chip's PMEN pin 15 16Optional properties: 17- ti,wl1251-has-eeprom : boolean, the wl1251 has an eeprom connected, which 18 provides configuration data (calibration, MAC, ...) 19- Please consult Documentation/devicetree/bindings/spi/spi-bus.txt 20 for optional SPI connection related properties, 21 22Examples: 23 24&spi1 { 25 wl1251@0 { 26 compatible = "ti,wl1251"; 27 28 reg = <0>; 29 spi-max-frequency = <48000000>; 30 spi-cpol; 31 spi-cpha; 32 33 interrupt-parent = <&gpio2>; 34 interrupts = <10 IRQ_TYPE_NONE>; /* gpio line 42 */ 35 36 vio-supply = <&vio>; 37 ti,power-gpio = <&gpio3 23 GPIO_ACTIVE_HIGH>; /* 87 */ 38 }; 39}; 40
