| 2 | |
| 3 | Required properties: |
| 4 | - compatible : should be "atmel,at91rm9200-spi". |
| 5 | - reg: Address and length of the register set for the device |
| 6 | - interrupts: Should contain spi interrupt |
| 7 | - cs-gpios: chipselects |

| 9 | Required elements: "spi_clk" |
| 10 | - clocks: phandles to input clocks. |
