PXA2xx SSP SPI Controller Required properties: - compatible: Must be "marvell,mmp2-ssp". - reg: Offset and length of the device's register set. - interrupts: Should be the interrupt number. - clocks: Should contain a single entry describing the clock input. - #address-cells: Number of cells required to define a chip select address. - #size-cells: Should be zero. Optional properties: - cs-gpios: list of GPIO chip selects. See the SPI bus bindings, Documentation/devicetree/bindings/spi/spi-bus.txt - spi-slave: Empty property indicating the SPI controller is used in slave mode. - ready-gpios: GPIO used to signal a SPI master that the FIFO is filled and we're ready to service a transfer. Only useful in slave mode. Child nodes represent devices on the SPI bus See ../spi/spi-bus.txt Example: ssp1: spi@d4035000 { compatible = "marvell,mmp2-ssp"; reg = <0xd4035000 0x1000>; clocks = <&soc_clocks MMP2_CLK_SSP0>; interrupts = <0>; };
