1Cadence SPI controller Device Tree Bindings
2-------------------------------------------
3
4Required properties:
5- compatible		: Should be "cdns,spi-r1p6" or "xlnx,zynq-spi-r1p6".
6- reg			: Physical base address and size of SPI registers map.
7- interrupts		: Property with a value describing the interrupt
8			  number.
9- interrupt-parent	: Must be core interrupt controller
10- clock-names		: List of input clock names - "ref_clk", "pclk"
11			  (See clock bindings for details).
12- clocks		: Clock phandles (see clock bindings for details).
13
14Optional properties:
15- num-cs		: Number of chip selects used.
16			  If a decoder is used, this will be the number of
17			  chip selects after the decoder.
18- is-decoded-cs		: Flag to indicate whether decoder is used or not.

21
22	spi@e0007000 {
23		compatible = "xlnx,zynq-spi-r1p6";
24		clock-names = "ref_clk", "pclk";
25		clocks = <&clkc 26>, <&clkc 35>;
26		interrupt-parent = <&intc>;
27		interrupts = <0 49 4>;
28		num-cs = <4>;
29		is-decoded-cs = <0>;
30		reg = <0xe0007000 0x1000>;
