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. 8 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. 31 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}; 50
