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.
- interrupt-parent : Must be core interrupt controller
- 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>;
} ;
