+Device-Tree bindings for mixer driver
+
+Required properties:
+- compatible: value should be "samsung,exynos5-mixer".
+- reg: physical base address of the mixer and length of memory mapped
+	region.
+- interrupts: interrupt number to the cpu.
+
+Example:
+
+	mixer {
+		compatible = "samsung,exynos5-mixer";
+		reg = <0x14450000 0x10000>;
+		interrupts = <0 94 0>;
