  • 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

  • reg : Physical base address of the IP registers and length of memory
    mapped region.

  • interrupts : MFC interrupt number to the CPU.

  • samsung,mfc-r : Base address of the first memory bank used by MFC

        for DMA contiguous memory allocation and its size.
    
  • samsung,mfc-l : Base address of the second memory bank used by MFC

        for DMA contiguous memory allocation and its size.
    

Optional properties:

  • samsung,power-domain : power-domain property defined with a phandle
           to respective power domain.
    

Example:
SoC specific DT entry:

mfc: codec@13400000 {
compatible = “samsung,mfc-v5”;
reg = <0x13400000 0x10000>;
interrupts = <0 94 0>;
samsung,power-domain = <&pd_mfc>;
};

Board specific DT entry:

codec@13400000 {
samsung,mfc-r = <0x43000000 0x800000>;
samsung,mfc-l = <0x51000000 0x800000>;
};
