+* Samsung 2D Graphics Accelerator
+
+Required properties:
+ - compatible : value should be one among the following:
+ (a) "samsung,s5pv210-g2d" for G2D IP present in S5PV210 & Exynos4210 SoC
+ (b) "samsung,exynos4212-g2d" for G2D IP present in Exynos4x12 SoCs
+ (c) "samsung,exynos5250-g2d" for G2D IP present in Exynos5250 SoC
+
+ - reg : Physical base address of the IP registers and length of memory
+ mapped region.
+
+ - interrupts : G2D interrupt number to the CPU.
+
+Example:
+ g2d@12800000 {
+ compatible = "samsung,s5pv210-g2d";
+ reg = <0x12800000 0x1000>;
+ interrupts = <0 89 0>;
+ status = "disabled";
+ };
