3Required properties:
4- compatible: Should be "sprd,sc9860-spi".
5- reg: Offset and length of SPI controller register space.
6- interrupts: Should contain SPI interrupt.
7- clock-names: Should contain following entries:
8	"spi" for SPI clock,
9	"source" for SPI source (parent) clock,
10	"enable" for SPI module enable clock.
11- clocks: List of clock input name strings sorted in the same order
12	as the clock-names property.
13- #address-cells: The number of cells required to define a chip select
14	address on the SPI bus. Should be set to 1.
15- #size-cells: Should be set to 0.

18spi0: spi@70a00000{
19	compatible = "sprd,sc9860-spi";
20	reg = <0 0x70a00000 0 0x1000>;
21	interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
22	clock-names = "spi", "source","enable";
23	clocks = <&clk_spi0>, <&ext_26m>, <&clk_ap_apb_gates 5>;
24	#address-cells = <1>;
25	#size-cells = <0>;
