-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@...30000 {
-		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>;
