| +* 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>; |
