1Allwinner A31 SPI controller
2
3Required properties:
4- compatible: Should be "allwinner,sun6i-a31-spi".
5- reg: Should contain register location and length.
6- interrupts: Should contain interrupt.
7- clocks: phandle to the clocks feeding the SPI controller. Two are
8 needed:
9 - "ahb": the gated AHB parent clock
10 - "mod": the parent module clock
11- clock-names: Must contain the clock names described just above
12- resets: phandle to the reset controller asserting this device in
13 reset

15Example:
16
17spi1: spi@01c69000 {
18 compatible = "allwinner,sun6i-a31-spi";
19 reg = <0x01c69000 0x1000>;
20 interrupts = <0 66 4>;
21 clocks = <&ahb1_gates 21>, <&spi1_clk>;
22 clock-names = "ahb", "mod";
23 resets = <&ahb1_rst 21>;
24};
