+Macronix MX25F0A MultiFunction Device Tree Bindings
+----------------------------------------------------
+
+MX25F0A is a MultiFunction Device with SPI and raw NAND, which
+supports either spi host controller or raw nand controller.
+
+Required properties:
+- compatible: should be "mxic,mx25f0a"
+- #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 in SPI mode.
+- reg-names: should contain "regs" and "dirmap"
+- interrupts: interrupt line connected to this MFD controller
+- SPI controller driver:
+ - 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
+
+- Raw nand controller driver.
+ - nand-ecc-mode = "soft";
+ - nand-ecc-algo = "bch";
+
+Example:
+
+ mxic: mx25f0a@43c30000 {
+ compatible = "mxic,mx25f0a";
+ reg = <0x43c30000 0x10000>, <0xa0000000 0x4000000>;
+ reg-names = "regs", "dirmap";
+
+ /* spi */
+ clocks = <&clkwizard 0>, <&clkwizard 1>, <&clkc 15>;
+ 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>;
+ };
+
+ /* nand */
+ nand-ecc-mode = "soft";
+ nand-ecc-algo = "bch";
+ nand-ecc-step-size = <512>;
+ nand-ecc-strength = <8>;
+ };
