1	* Samsung Multi Format Codec (MFC)
2	
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
7	video codecs.
8	
9	Required 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		(b) "samsung,mfc-v7" for MFC v7 present in Exynos5420 SoC
14	
15	  - reg : Physical base address of the IP registers and length of memory
16		  mapped region.
17	
18	  - interrupts : MFC interrupt number to the CPU.
19	  - clocks : from common clock binding: handle to mfc clock.
20	  - clock-names : from common clock binding: must contain "mfc",
21			  corresponding to entry in the clocks property.
22	
23	  - samsung,mfc-r : Base address of the first memory bank used by MFC
24			    for DMA contiguous memory allocation and its size.
25	
26	  - samsung,mfc-l : Base address of the second memory bank used by MFC
27			    for DMA contiguous memory allocation and its size.
28	
29	Optional properties:
30	  - samsung,power-domain : power-domain property defined with a phandle
31				   to respective power domain.
32	
33	Example:
34	SoC specific DT entry:
35	
36	mfc: codec@13400000 {
37		compatible = "samsung,mfc-v5";
38		reg = <0x13400000 0x10000>;
39		interrupts = <0 94 0>;
40		samsung,power-domain = <&pd_mfc>;
41		clocks = <&clock 273>;
42		clock-names = "mfc";
43	};
44	
45	Board specific DT entry:
46	
47	codec@13400000 {
48		samsung,mfc-r = <0x43000000 0x800000>;
49		samsung,mfc-l = <0x51000000 0x800000>;
50	};
