Subject: [PATCH v2] dt-bindings: gpu: Convert Samsung 2D Graphics
Accelerator to dt-schema
From: Maciej Falkowski <m.falkowski@...sung.com>
Convert Samsung 2D Graphics Accelerator to newer dt-schema format
Signed-off-by: Maciej Falkowski <m.falkowski@...sung.com>
Signed-off-by: Marek Szyprowski <m.szyprowski@...sung.com>

-* 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.
- - clocks : from common clock binding: handle to G2D clocks.
- - clock-names : names of clocks listed in clocks property, in the same
- order, depending on SoC type:
- - for S5PV210 and Exynos4 based SoCs: "fimg2d" and
- "sclk_fimg2d"
- - for Exynos5250 SoC: "fimg2d".
-
-Example:
- g2d@...00000 {
- compatible = "samsung,s5pv210-g2d";
- reg = <0x12800000 0x1000>;
- interrupts = <0 89 0>;
- clocks = <&clock 177>, <&clock 277>;
- clock-names = "sclk_fimg2d", "fimg2d";
- };
