+Macronix Raw NAND Controller Device Tree Bindings
+-------------------------------------------------
+
+Required properties:
+- compatible: should be "macronix,nand-controller"
+- reg: should contain 1 entrie for the registers
+- interrupts: interrupt line connected to this raw NAND controller
+- clock-names: should contain "ps_clk", "send_clk" and "send_dly_clk"
+- clocks: should contain 3 phandles for the "ps_clk", "send_clk" and
+ "send_dly_clk" clocks
+
+Example:
+
+ nand: mxic-nfc@43c30000 {
The node names should be generic, and the DT spec 0.2 (section 2.2.2) even
has documented "nand-controller", please rename.
+ compatible = "macronix,nand-controller";
+ reg = <0x43c30000 0x10000>;
+ reg-names = "regs";
+ clocks = <&clkwizard 0>, <&clkwizard 1>, <&clkc 15>;
+ clock-names = "send_clk", "send_dly_clk", "ps_clk";
+ };
