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- spi-max-frequency	: Maximum SPI clocking speed of device in Hz
14
15Optional properties:
16- num-cs		: Number of chip selects used.
17			  If a decoder is used, this will be the number of
18			  chip selects after the decoder.
19- is-decoded-cs		: Flag to indicate whether decoder is used or not.

21Example:
22
23	spi@e0007000 {
24		compatible = "xlnx,zynq-spi-r1p6";
25		clock-names = "ref_clk", "pclk";
26		clocks = <&clkc 26>, <&clkc 35>;
27		interrupt-parent = <&intc>;
28		interrupts = <0 49 4>;
29		num-cs = <4>;
30		is-decoded-cs = <0>;
31		reg = <0xe0007000 0x1000>;
32	} ;
