    1 * Texas Instruments wl1251 wireless lan controller
    2 
    3 The wl1251 chip can be connected via SPI or via SDIO. This
    4 document describes the binding for the SPI connected chip.
    5 
    6 Required 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 
   13 Optional properties:
   14 - ti,wl1251-has-eeprom : boolean, the wl1251 has an eeprom connected, which
   15                          provides configuration data (calibration, MAC, ...)
   16 - ti,power-gpio :        GPIO connected to chip's PMEN pin if operated in
   17                          SPI mode
   18 - Please consult Documentation/devicetree/bindings/spi/spi-bus.txt
   19   for optional SPI connection related properties,
   20
