1SPI-GPIO devicetree bindings
2
3Required 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             Not needed if num-chipselects = <0>.
13 - num-chipselects: Number of chipselect lines. Should be <0> if a single device
14                    with no chip select is connected.
