1PXA2xx SSP SPI Controller 2 3Required properties: 4- compatible: Must be "marvell,mmp2-ssp". 5- reg: Offset and length of the device's register set. 6- interrupts: Should be the interrupt number. 7- clocks: Should contain a single entry describing the clock input. 8- #address-cells: Number of cells required to define a chip select address. 9- #size-cells: Should be zero. 10 11Optional properties: 12- cs-gpios: list of GPIO chip selects. See the SPI bus bindings, 13 Documentation/devicetree/bindings/spi/spi-bus.txt 14- spi-slave: Empty property indicating the SPI controller is used in slave mode. 15- ready-gpios: GPIO used to signal a SPI master that the FIFO is filled 16 and we're ready to service a transfer. Only useful in slave mode. 17 18Child nodes represent devices on the SPI bus 19 See ../spi/spi-bus.txt 20 21Example: 22 ssp1: spi@d4035000 { 23 compatible = "marvell,mmp2-ssp"; 24 reg = <0xd4035000 0x1000>; 25 clocks = <&soc_clocks MMP2_CLK_SSP0>; 26 interrupts = <0>; 27 }; 28
