    +* 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";
    + };
