+* Samsung Exynos5 G-Scaler device
+
+G-Scaler is used for scaling and color space conversion on EXYNOS5 SoCs.
+
+Required properties:
+- compatible: should be "samsung,exynos5-gsc"
+- reg: should contain G-Scaler physical address location and length.
+- interrupts: should contain G-Scaler interrupt number
+
+Example:
+
+gsc_0: gsc@0x13e00000 {
+ compatible = "samsung,exynos5-gsc";
+ reg = <0x13e00000 0x1000>;
+ interrupts = <0 85 0>;
+};
+
+Aliases:
+Each G-Scaler node should have a numbered alias in the aliases node,
+in the form of gscN, N = 0...3. G-Scaler driver uses these aliases
+to retrieve the device IDs using "of_alias_get_id()" call.
+
+Example:
+
+aliases {
+ gsc0 =&gsc_0;
+ gsc1 =&gsc_1;
+ gsc2 =&gsc_2;
+ gsc3 =&gsc_3;
+};

+* 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.
