-* 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@...00000 {
- 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@...00000 {
- compatible = "shared-dma-pool";
- no-map;
- reg = <0x51000000 0x800000>;
- };
-
- mfc_right: region@...00000 {
- compatible = "shared-dma-pool";
- no-map;
- reg = <0x43000000 0x800000>;
- };
-};
-
-Board specific DT entry:
-
-codec@...00000 {
- memory-region = <&mfc_left>, <&mfc_right>;
-};
