* Renesas VSP Video Processing Engine
|
|
|
|
The VSP is a video processing engine that supports up-/down-scaling, alpha
|
|
blending, color space conversion and various other image processing features.
|
|
It can be found in the Renesas R-Car second generation SoCs.
|
|
|
|
Required properties:
|
|
|
|
- compatible: Must contain one of the following values
|
|
- "renesas,vsp1" for the R-Car Gen2 VSP1
|
|
- "renesas,vsp2" for the R-Car Gen3 VSP2
|
|
|
|
- reg: Base address and length of the registers block for the VSP.
|
|
- interrupts: VSP interrupt specifier.
|
|
- clocks: A phandle + clock-specifier pair for the VSP functional clock.
|
|
|
|
- renesas,#rpf: Number of Read Pixel Formatter (RPF) modules in the VSP.
|
|
- renesas,#wpf: Number of Write Pixel Formatter (WPF) modules in the VSP.
|
|
|
|
|
|
Optional properties:
|
|
|
|
- renesas,#uds: Number of Up Down Scaler (UDS) modules in the VSP. Defaults
|
|
to 0 if not present.
|
|
- renesas,has-lif: Boolean, indicates that the LCD Interface (LIF) module is
|
|
available.
|
|
- renesas,has-lut: Boolean, indicates that the Look Up Table (LUT) module is
|
|
available.
|
|
- renesas,has-sru: Boolean, indicates that the Super Resolution Unit (SRU)
|
|
module is available.
|
|
|
|
|
|
Example: R8A7790 (R-Car H2) VSP1-S node
|
|
|
|
vsp1@fe928000 {
|
|
compatible = "renesas,vsp1";
|
|
reg = <0 0xfe928000 0 0x8000>;
|
|
interrupts = <0 267 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&mstp1_clks R8A7790_CLK_VSP1_S>;
|
|
|
|
renesas,has-lut;
|
|
renesas,has-sru;
|
|
renesas,#rpf = <5>;
|
|
renesas,#uds = <3>;
|
|
renesas,#wpf = <4>;
|
|
};
