1	* Samsung Exynos5 G-Scaler device
2	
3	G-Scaler is used for scaling and color space conversion on EXYNOS5 SoCs.
4	
5	Required properties:
6	- compatible: should be "samsung,exynos5-gsc" (for Exynos 5250, 5420 and
7		      5422 SoCs) or "samsung,exynos5433-gsc" (Exynos 5433)
8	- reg: should contain G-Scaler physical address location and length.
9	- interrupts: should contain G-Scaler interrupt number
10	
11	Optional properties:
12	- samsung,sysreg: handle to syscon used to control the system registers to
13	  set writeback input and destination
14	
15	Example:
16	
17	gsc_0:  gsc@0x13e00000 {
18		compatible = "samsung,exynos5-gsc";
19		reg = <0x13e00000 0x1000>;
20		interrupts = <0 85 0>;
21	};
22	
23	Aliases:
24	Each G-Scaler node should have a numbered alias in the aliases node,
25	in the form of gscN, N = 0...3. G-Scaler driver uses these aliases
26	to retrieve the device IDs using "of_alias_get_id()" call.
27	
28	Example:
29	
30	aliases {
31		gsc0 =&gsc_0;
32		gsc1 =&gsc_1;
33		gsc2 =&gsc_2;
34		gsc3 =&gsc_3;
35	};
