+Ingenic JZ EFUSE driver bindings
+
+Required properties:
+- "compatible" Must be set to "ingenic,jz4780-efuse"
+- "reg" Register location and length
+- "clocks" Handle for the ahb clock for the efuse.
+- "clock-names" Must be "bus_clk"
+
+Example:
+
+efuse: efuse@134100d0 {
+ compatible = "ingenic,jz4780-efuse";
+ reg = <0x134100d0 0x2c>;
+
+ clocks = <&cgu JZ4780_CLK_AHB2>;
+ clock-names = "bus_clk";
