   1* Samsung Multi Format Codec (MFC)
   2
   3Multi Format Codec (MFC) is the IP present in Samsung SoCs which
   4supports high resolution decoding and encoding functionalities.
   5The MFC device driver is a v4l2 driver which can encode/decode
   6video raw/elementary streams and has support for all popular
   7video codecs.

   9Required properties:
  10  - compatible : value should be either one among the following
  11        (a) "samsung,mfc-v5" for MFC v5 present in Exynos4 SoCs
  12        (b) "samsung,mfc-v6" for MFC v6 present in Exynos5 SoCs
  13
  14  - reg : Physical base address of the IP registers and length of memory
  15          mapped region.
  16
  17  - interrupts : MFC interrupt number to the CPU.
  18  - clocks : from common clock binding: handle to mfc clocks.
  19  - clock-names : from common clock binding: must contain "sclk_mfc" and "mfc",
  20                  corresponding to entries in the clocks property.
  21
  22  - samsung,mfc-r : Base address of the first memory bank used by MFC
  23                    for DMA contiguous memory allocation and its size.
  24
  25  - samsung,mfc-l : Base address of the second memory bank used by MFC
  26                    for DMA contiguous memory allocation and its size.
  27
  28Optional properties:
  29  - samsung,power-domain : power-domain property defined with a phandle
  30                           to respective power domain.

  32Example:
  33SoC specific DT entry:
  34
  35mfc: codec@13400000 {
  36        compatible = "samsung,mfc-v5";
  37        reg = <0x13400000 0x10000>;
  38        interrupts = <0 94 0>;
  39        samsung,power-domain = <&pd_mfc>;
  40        clocks = <&clock 170>, <&clock 273>;
  41        clock-names = "sclk_mfc", "mfc";
  42};
  43
  44Board specific DT entry:
  45
  46codec@13400000 {
  47        samsung,mfc-r = <0x43000000 0x800000>;
  48        samsung,mfc-l = <0x51000000 0x800000>;
  49};
