    -* Samsung Multi Format Codec (MFC)
    -
    -Multi Format Codec (MFC) is the IP present in Samsung SoCs which
    -supports high resolution decoding and encoding functionalities.
    -The MFC device driver is a v4l2 driver which can encode/decode
    -video raw/elementary streams and has support for all popular
    -video codecs.
    -
    -Required properties:
    - - compatible : value should be either one among the following
    - (a) "samsung,mfc-v5" for MFC v5 present in Exynos4 SoCs
    - (b) "samsung,mfc-v6" for MFC v6 present in Exynos5 SoCs
    - (c) "samsung,mfc-v7" for MFC v7 present in Exynos5420 SoC
    - (d) "samsung,mfc-v8" for MFC v8 present in Exynos5800 SoC
    - (e) "samsung,exynos5433-mfc" for MFC v8 present in Exynos5433 SoC
    - (f) "samsung,mfc-v10" for MFC v10 present in Exynos7880 SoC
    -
    - - reg : Physical base address of the IP registers and length of memory
    - mapped region.
    -
    - - interrupts : MFC interrupt number to the CPU.
    - - clocks : from common clock binding: handle to mfc clock.
    - - clock-names : from common clock binding: must contain "mfc",
    - corresponding to entry in the clocks property.
    -
    -Optional properties:
    - - power-domains : power-domain property defined with a phandle
    - to respective power domain.
    - - memory-region : from reserved memory binding: phandles to two reserved
    - memory regions, first is for "left" mfc memory bus interfaces,
    - second if for the "right" mfc memory bus, used when no SYSMMU
    - support is available; used only by MFC v5 present in Exynos4 SoCs
    -
    -Obsolete properties:
    - - samsung,mfc-r, samsung,mfc-l : support removed, please use memory-region
    - property instead
    -
    -
    -Example:
    -SoC specific DT entry:
    -
    -mfc: codec@13400000 {
    - compatible = "samsung,mfc-v5";
    - reg = <0x13400000 0x10000>;
    - interrupts = <0 94 0>;
    - power-domains = <&pd_mfc>;
    - clocks = <&clock 273>;
    - clock-names = "mfc";
    -};
    -
    -Reserved memory specific DT entry for given board (see reserved memory binding
    -for more information):
    -
    -reserved-memory {
    - #address-cells = <1>;
    - #size-cells = <1>;
    - ranges;
    -
    - mfc_left: region@51000000 {
    - compatible = "shared-dma-pool";
    - no-map;
    - reg = <0x51000000 0x800000>;
    - };
    -
    - mfc_right: region@43000000 {
    - compatible = "shared-dma-pool";
    - no-map;
    - reg = <0x43000000 0x800000>;
    - };
    -};
    -
    -Board specific DT entry:
    -
    -codec@13400000 {
    - memory-region = <&mfc_left>, <&mfc_right>;
    -};
