6 Required properties:
7 - compatible :          Should be "ti,wl1271"
8 - reg :                 Chip select address of device
9 - spi-max-frequency :   Maximum SPI clocking speed of device in Hz
10 - ref-clock-frequency : Reference clock frequency
11 - interrupt-parent, interrupts :
12                         Should contain parameters for 1 interrupt line.
13                         Interrupt parameters: parent, line number, type.
14 - vwlan-supply :        Point the node of the regulator that powers/enable the wl1271 chip
15
16 Optional properties:
17 - clock-xtal :          boolean, clock is generated from XTAL
