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- vio-supply :        phandle to regulator providing VIO
12- ti,power-gpio :     GPIO connected to chip's PMEN pin
13
14Optional 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,
