* 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



  - reg : Physical base address of the IP registers and length of memory

	  mapped region.



  - interrupts : MFC interrupt number to the CPU.



  - 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.
