+* Samsung video/graphics mixer and blender
+
+Mixer blends graphics data from multiple sources and sends resulting
+data to TVOUT module.
+
+
+Required properties:
+
+ - compatible : "samsung,s5pv210-tvmixer"
+ - reg : shall contain memory addresses and sizes of mixer and video
+ processor devices
+ - reg-names : "mxr" for mixer's address/size and "vp" to for video
+ processor's.
+ - interrupt-names : shall contain "irq"
+
+
+Example:
+
+ tvmixer@12c10000 {
+ compatible = "samsung,s5pv210-tvmixer";
+ reg = <0x12c10000 0x10000>,
+ <0x12c00000 0x10000>;
+ reg-names = "mxr", "vp";
+ interrupts = <0 123 0>;
+ interrupt-names = "irq";
+ };
