| * 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 */ |
| }; |
| }; |
