- 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.
- memory-region : from reserved memory binding: phandles to two reserved
memory regions, first is for "left" mfc memory bus interfaces,
second if for the "right" mfc memory bus, used when no SYSMMU
support is available
Obsolete properties:
- samsung,mfc-r, samsung,mfc-l : support removed, please use memory-region
property instead
