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:
|
||
|
|
- compatible: value should be one of the following
|
||
|
|
"rockchip,rk3288-rga";
|
||
|
|
"rockchip,rk3399-rga";
|
||
|
|
|
||
|
|
- 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.
|
||
|
|
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>;
|
||
|
|
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";
|
||
|
|
};
