1 * Rockchip SPI Controller
3 The Rockchip SPI controller is used to interface with various devices such as flash
4 and display controllers using the SPI communication interface.
8 - compatible: should be one of the following.
9 "rockchip,rk3066-spi" for rk3066.
10 "rockchip,rk3188-spi", "rockchip,rk3066-spi" for rk3188.
11 "rockchip,rk3288-spi", "rockchip,rk3066-spi" for rk3288.
12 - reg: physical base address of the controller and length of memory mapped
14 - interrupts: The interrupt number to the cpu. The interrupt specifier format
15 depends on the interrupt controller.
16 - clocks: Must contain an entry for each entry in clock-names.
17 - clock-names: Shall be "spiclk" for the transfer-clock, and "apb_pclk" for
19 - dmas: DMA specifiers for tx and rx dma. See the DMA client binding,
20 Documentation/devicetree/bindings/dma/dma.txt
21 - dma-names: DMA request names should include "tx" and "rx" if present.
22 - #address-cells: should be 1.
23 - #size-cells: should be 0.
