-Xilinx Zynq QSPI controller Device Tree Bindings
--------------------------------------------------------------------
-
-Required properties:
-- compatible : Should be "xlnx,zynq-qspi-1.0".
-- reg : Physical base address and size of QSPI 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.
-
-Example:
- qspi: spi@e000d000 {
- compatible = "xlnx,zynq-qspi-1.0";
- reg = <0xe000d000 0x1000>;
- interrupt-parent = <&intc>;
- interrupts = <0 19 4>;
- clock-names = "ref_clk", "pclk";
- clocks = <&clkc 10>, <&clkc 43>;
- num-cs = <1>;
- };
