- * 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
- - 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.
- - 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:
- - power-domains : 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>;
- power-domains = <&pd_mfc>;
- clocks = <&clock 273>;
- clock-names = "mfc";
- };
- Board specific DT entry:
- codec@13400000 {
- samsung,mfc-r = <0x43000000 0x800000>;
- samsung,mfc-l = <0x51000000 0x800000>;
- };
