| * Texas Instruments wl1271 wireless lan controller |
| |
| 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>; |
| }; |
| }; |
