   1 device-tree bindings for rockchip 2D raster graphic acceleration controller (RGA)
   2
   3 RGA is a separate 2D raster graphic acceleration unit. It accelerates 2D
   4 graphics operations, such as point/line drawing, image scaling, rotation,
   5 BitBLT, alpha blending and image blur/sharpness.
   6
   7 Required properties:
   8 - compatible: value should be one of the following
   9                 "rockchip,rk3228-rga";
  10                 "rockchip,rk3288-rga";
  11                 "rockchip,rk3399-rga";
  12
  13 - interrupts: RGA interrupt number.
  14
  15 - clocks: phandle to RGA sclk/hclk/aclk clocks
  16
  17 - clock-names: should be "aclk" "hclk" and "sclk"
  18
  19 - resets: Must contain an entry for each entry in reset-names.
  20   See ../reset/reset.txt for details.
  21 - reset-names: should be "core" "axi" and "ahb"
  22
  23 Example:
  24 SoC specific DT entry:
  25         rga: rga@ff680000 {
  26                 compatible = "rockchip,rk3399-rga";
  27                 reg = <0xff680000 0x10000>;
  28                 interrupts = <GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>;
  29                 interrupt-names = "rga";
  30                 clocks = <&cru ACLK_RGA>, <&cru HCLK_RGA>, <&cru SCLK_RGA_CORE>;
  31                 clock-names = "aclk", "hclk", "sclk";
  32
  33                 resets = <&cru SRST_RGA_CORE>, <&cru SRST_A_RGA>, <&cru SRST_H_RGA>;
  34                 reset-names = "core, "axi", "ahb";
  35                 status = "disabled";
