| * 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>; |
| }; |
