-device-tree bindings for rockchip 2D raster graphic acceleration controller (RGA)
-
-RGA is a separate 2D raster graphic acceleration unit. It accelerates 2D
-graphics operations, such as point/line drawing, image scaling, rotation,
-BitBLT, alpha blending and image blur/sharpness.
-
-Required properties:
-- compatible: value should be one of the following
-               "rockchip,rk3228-rga";
-               "rockchip,rk3288-rga";
-               "rockchip,rk3399-rga";
-
-- interrupts: RGA interrupt number.
-
-- clocks: phandle to RGA sclk/hclk/aclk clocks
-
-- clock-names: should be "aclk" "hclk" and "sclk"
-
-- resets: Must contain an entry for each entry in reset-names.
-  See ../reset/reset.txt for details.
-- reset-names: should be "core" "axi" and "ahb"
-
-Example:
-SoC specific DT entry:
-       rga: rga@ff680000 {
-               compatible = "rockchip,rk3399-rga";
-               reg = <0xff680000 0x10000>;
-               interrupts = <GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>;
-               interrupt-names = "rga";
-               clocks = <&cru ACLK_RGA>, <&cru HCLK_RGA>, <&cru SCLK_RGA_CORE>;
-               clock-names = "aclk", "hclk", "sclk";
-
-               resets = <&cru SRST_RGA_CORE>, <&cru SRST_A_RGA>, <&cru SRST_H_RGA>;
-               reset-names = "core, "axi", "ahb";
-               status = "disabled";
-       };

+device-tree bindings for rockchip 2D raster graphic acceleration controller (RGA)
+
+RGA is a standalone 2D raster graphic acceleration unit. It accelerates 2D
+graphics operations, such as point/line drawing, image scaling, rotation,
+BitBLT, alpha blending and image blur/sharpness.

+Required properties:

+- interrupts: RGA interrupt specifier.

+- clocks: phandle to RGA sclk/hclk/aclk clocks

+- clock-names: should be "aclk", "hclk" and "sclk"

+- resets: Must contain an entry for each entry in reset-names.
