* 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.
- clocks : from common clock binding: handle to mfc clocks.
- clock-names : from common clock binding: must contain "sclk_mfc" and "mfc",
corresponding to entries 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:
- samsung,power-domain : power-domain property defined with a phandle
to respective power domain.
Example:
SoC specific DT entry:
mfc: codec@13400000 {
compatible = "samsung,mfc-v5";
reg = <0x13400000 0x10000>;
interrupts = <0 94 0>;
samsung,power-domain = <&pd_mfc>;
clocks = <&clock 170>, <&clock 273>;
clock-names = "sclk_mfc", "mfc";
};
Board specific DT entry:
codec@13400000 {
samsung,mfc-r = <0x43000000 0x800000>;
samsung,mfc-l = <0x51000000 0x800000>;
};
