|
||||
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 "renesas,vsp1"
|
||||
- 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 VSP1.
|
||||
- interrupts: VSP1 interrupt specifier.
|
||||
- clocks: A phandle + clock-specifier pair for the VSP1 functional clock.

||||
- 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 VSP1.
|
||||
- renesas,#wpf: Number of Write Pixel Formatter (WPF) modules in the VSP1.
|
||||

||||
Optional properties:
|
||||
|
||||
- renesas,#uds: Number of Up Down Scaler (UDS) modules in the VSP1. Defaults
|
||||
- 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.
