   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 - ti,power-gpio :     GPIO connected to chip's PMEN pin
  13
  14 Optional 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,
