-Spreadtrum SPI Controller
-
-Required properties:
-- compatible: Should be "sprd,sc9860-spi".
-- reg: Offset and length of SPI controller register space.
-- interrupts: Should contain SPI interrupt.
-- clock-names: Should contain following entries:
-	"spi" for SPI clock,
-	"source" for SPI source (parent) clock,
-	"enable" for SPI module enable clock.
-- clocks: List of clock input name strings sorted in the same order
-	as the clock-names property.
-- #address-cells: The number of cells required to define a chip select
-	address on the SPI bus. Should be set to 1.
-- #size-cells: Should be set to 0.
-
-Optional properties:
-dma-names: Should contain names of the SPI used DMA channel.
-dmas: Should contain DMA channels and DMA slave ids which the SPI used
-	sorted in the same order as the dma-names property.
-
-Example:
-spi0: spi@70a00000{
-	compatible = "sprd,sc9860-spi";
-	reg = <0 0x70a00000 0 0x1000>;
-	interrupts = <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>;
-	clock-names = "spi", "source","enable";
-	clocks = <&clk_spi0>, <&ext_26m>, <&clk_ap_apb_gates 5>;
-	dma-names = "rx_chn", "tx_chn";
-	dmas = <&apdma 11 11>, <&apdma 12 12>;
-	#address-cells = <1>;
-	#size-cells = <0>;
-};
