Macronix SPI controller Device Tree Bindings

--------------------------------------------

Required properties:

- compatible: should be "mxicy,mx25f0a-spi"

- #address-cells: should be 1

- #size-cells: should be 0

- reg: should contain 2 entries, one for the registers and one for the direct

       mapping area

- reg-names: should contain "regs" and "dirmap"

- clock-names: should contain "ps_clk", "send_clk" and "send_dly_clk"

- clocks: should contain 3 entries for the "ps_clk", "send_clk" and

	  "send_dly_clk" clocks

Optional properties:

- interrupts: interrupt line connected to the SPI controller

Example:

	spi@43c30000 {

		compatible = "mxicy,mx25f0a-spi";

		reg = <0x43c30000 0x10000>, <0xa0000000 0x20000000>;

		reg-names = "regs", "dirmap";

		clocks = <&clkwizard 0>, <&clkwizard 1>, <&clkc 18>;

		clock-names = "send_clk", "send_dly_clk", "ps_clk";

		#address-cells = <1>;

		#size-cells = <0>;

		flash@0 {

			compatible = "jedec,spi-nor";

			reg = <0>;

			spi-max-frequency = <25000000>;

			spi-tx-bus-width = <4>;

			spi-rx-bus-width = <4>;

		};
