1* Samsung Multi Format Codec (MFC)
2
3Multi Format Codec (MFC) is the IP present in Samsung SoCs which
4supports high resolution decoding and encoding functionalities.
5The MFC device driver is a v4l2 driver which can encode/decode
6video raw/elementary streams and has support for all popular
7video codecs.

9Required 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
29Optional properties:
30  - samsung,power-domain : power-domain property defined with a phandle
31			   to respective power domain.
