* Renesas VSP1 Video Processing Engine
The VSP1 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 "renesas,vsp1"
- reg: Base address and length of the registers block for the VSP1.
- interrupts: VSP1 interrupt specifier.
- clocks: A phandle + clock-specifier pair for the VSP1 functional clock.
- renesas,#rpf: Number of Read Pixel Formatter (RPF) modules in the VSP1.
- renesas,#uds: Number of Up Down Scaler (UDS) modules in the VSP1.
- renesas,#wpf: Number of Write Pixel Formatter (WPF) modules in the VSP1.
Optional properties:
- 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>;
};
