* 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>; };
