Pull ARM SoC DT updates from Olof Johansson:
"Device tree and bindings updates for 3.12.
General additions of various on-chip and on-board peripherals on
various platforms as support gets added. Some of the bigger changes
are:
- Addition of (new) PCI-e support on Tegra.
- More Tegra4 support, including PMC configuration for Dalmore.
- Addition of a new board for Exynos4 (trats2) and more bindings for
4x12 IP.
- Addition of Allwinner A20 and A31 SoC and board files.
- Move of the ST Ericsson device tree files to now use ste-* prefix.
- More move of hardware description of shmobile platforms to DT.
- Two new board dts files for Freescale MXs"

* 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
|
|
(b) "samsung,mfc-v7" for MFC v7 present in Exynos5420 SoC
|
|
|
|
- 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 clock.
|
|
- 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:
|
|
- 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 273>;
|
|
clock-names = "mfc";
|
|
};
|
|
|
|
Board specific DT entry:
|
|
|
|
codec@13400000 {
|
|
samsung,mfc-r = <0x43000000 0x800000>;
|
|
samsung,mfc-l = <0x51000000 0x800000>;
|
|
};
