2	
3	Required properties:
4	
5	 - compatible: should be set to "spi-gpio"
6	 - #address-cells: should be set to <0x1>
7	 - ranges
8	 - gpio-sck: GPIO spec for the SCK line to use
9	 - gpio-miso: GPIO spec for the MISO line to use
10	 - gpio-mosi: GPIO spec for the MOSI line to use
11	 - cs-gpios: GPIOs to use for chipselect lines
12	 - num-chipselects: number of chipselect lines
