| 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 |
