1* Marvell Armada 3700 SPI Controller
2
3Required Properties:
4
5- compatible: should be "marvell,armada-3700-spi"
6- reg: physical base address of the controller and length of memory mapped
7       region.
8- interrupts: The interrupt number. The interrupt specifier format depends on
9	      the interrupt controller and of its driver.
10- clocks: Must contain the clock source, usually from the North Bridge clocks.
11- num-cs: The number of chip selects that is supported by this SPI Controller
12- #address-cells: should be 1.
13- #size-cells: should be 0.

15Example:
16
17	spi0: spi@10600 {
18		compatible = "marvell,armada-3700-spi";
19		#address-cells = <1>;
20		#size-cells = <0>;
21		reg = <0x10600 0x5d>;
22		clocks = <&nb_perih_clk 7>;
23		interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>;
24		num-cs = <4>;
25	};
