-Cadence SPI controller Device Tree Bindings
--------------------------------------------
-
-Required properties:
-- compatible		: Should be "cdns,spi-r1p6" or "xlnx,zynq-spi-r1p6".
-- reg			: Physical base address and size of SPI registers map.
-- interrupts		: Property with a value describing the interrupt
-			  number.
-- clock-names		: List of input clock names - "ref_clk", "pclk"
-			  (See clock bindings for details).
-- clocks		: Clock phandles (see clock bindings for details).
-
-Optional properties:
-- num-cs		: Number of chip selects used.
-			  If a decoder is used, this will be the number of
-			  chip selects after the decoder.
-- is-decoded-cs		: Flag to indicate whether decoder is used or not.
-
-Example:
-
-	spi@e0007000 {
-		compatible = "xlnx,zynq-spi-r1p6";
-		clock-names = "ref_clk", "pclk";
-		clocks = <&clkc 26>, <&clkc 35>;
-		interrupt-parent = <&intc>;
-		interrupts = <0 49 4>;
-		num-cs = <4>;
-		is-decoded-cs = <0>;
-		reg = <0xe0007000 0x1000>;
-	} ;
