-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@...07000 {
- 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>;
- } ;
