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