1 * Samsung Multi Format Codec (MFC)
3 Multi Format Codec (MFC) is the IP present in Samsung SoCs which
4 supports high resolution decoding and encoding functionalities.
5 The MFC device driver is a v4l2 driver which can encode/decode
6 video raw/elementary streams and has support for all popular
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 (c) "samsung,mfc-v7" for MFC v7 present in Exynos5420 SoC
14 (d) "samsung,mfc-v8" for MFC v8 present in Exynos5800 SoC
16 - reg : Physical base address of the IP registers and length of memory
19 - interrupts : MFC interrupt number to the CPU.
20 - clocks : from common clock binding: handle to mfc clock.
21 - clock-names : from common clock binding: must contain "mfc",
22 corresponding to entry in the clocks property.
25 - power-domains : power-domain property defined with a phandle
26 to respective power domain.
27 - memory-region : from reserved memory binding: phandles to two reserved
28 memory regions, first is for "left" mfc memory bus interfaces,
29 second if for the "right" mfc memory bus, used when no SYSMMU
33 - samsung,mfc-r, samsung,mfc-l : support removed, please use memory-region
