SPI-GPIO devicetree bindings
Required properties:
- compatible: should be set to "spi-gpio"
- #address-cells: should be set to <0x1>
- ranges
- gpio-sck: GPIO spec for the SCK line to use
- gpio-miso: GPIO spec for the MISO line to use
- gpio-mosi: GPIO spec for the MOSI line to use
- cs-gpios: GPIOs to use for chipselect lines
- num-chipselects: number of chipselect lines
Example:
spi {
compatible = "spi-gpio";
#address-cells = <0x1>;
ranges;
gpio-sck = <&gpio 95 0>;
gpio-miso = <&gpio 98 0>;
gpio-mosi = <&gpio 97 0>;
cs-gpios = <&gpio 125 0>;
num-chipselects = <1>;
