+* Samsung 2D Graphics Accelerator
+
+Samsung FIMG2D is a 2D graphics accelerator which supports Bit Block Transfer.
+We set the drawing-context registers for configuring the rendering parameters
+and then start rendering.
+The G2D has V4L2 as well as DRM framework based driver support.
IMHO this whole paragraph is irrelevant and could be dropped.
+Required properties:
+ - compatible : value should be one among the following
missing colon at the end of line ?
+ (a) "samsung,s5pv210-g2d" for G2D IP present in S5PV210& Exynos4210 SoC
+ (b) "samsung,exynos4212-g2d" for G2D IP present in Exynos4x12 SoCs
+ (b) "samsung,exynos5250-g2d" for G2D IP present in Exynos5250 SoC
s/(b)/(c)
+
+ - reg : Physical base address of the IP registers and length of memory
+ mapped region.
+
+ - interrupts : G2D interrupt number to the CPU.
+
+Optional properties:
+ - samsung,power-domain : power-domain property defined with a phandle
+ to respective power domain.
+
+Example:
+ g2d@12800000 {
+ compatible = "samsung,s5pv210-g2d";
+ reg =<0x12800000 0x1000>;
+ interrupts =<0 89 0>;
+ samsung,power-domain =<&pd_lcd0>;
+ status = "disabled";
+ };
Otherwise looks good to me.
