+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"
+- interrupts: interrupt line connected to the SPI controller
+- 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
+
+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>;
+ };
+ };
