+Macronix Raw NAND Controller Device Tree Bindings
+-------------------------------------------------
+
+Required properties:
+- compatible: should be "mxic,raw-nand-ctlr"
+- reg: should contain 1 entrie for the registers
+- reg-names: should contain "regs"
+- interrupts: interrupt line connected to this NAND 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:
+
+ nand: mxic-nfc@43c30000 {
+ compatible = "mxic,raw-nand-ctlr";
+ reg = <0x43c30000 0x10000>;
+ reg-names = "regs";
+ clocks = <&clkwizard 0>, <&clkwizard 1>, <&clkc 15>;
+ clock-names = "send_clk", "send_dly_clk", "ps_clk";
+
+ nand-ecc-mode = "soft";
+ nand-ecc-algo = "bch";
+ nand-ecc-step-size = <512>;
+ nand-ecc-strength = <8>;
+ };
