-Allwinner A31/H3 SPI controller
-
-Required properties:
-- compatible: Should be "allwinner,sun6i-a31-spi" or "allwinner,sun8i-h3-spi".
-- reg: Should contain register location and length.
-- interrupts: Should contain interrupt.
-- clocks: phandle to the clocks feeding the SPI controller. Two are
- needed:
- - "ahb": the gated AHB parent clock
- - "mod": the parent module clock
-- clock-names: Must contain the clock names described just above
-- resets: phandle to the reset controller asserting this device in
- reset
-
-Optional properties:
-- dmas: DMA specifiers for rx and tx dma. See the DMA client binding,
- Documentation/devicetree/bindings/dma/dma.txt
-- dma-names: DMA request names should include "rx" and "tx" if present.
-
-Example:
-
-spi1: spi@1c69000 {
- compatible = "allwinner,sun6i-a31-spi";
- reg = <0x01c69000 0x1000>;
