+
+description:
+ The Rockchip RK3588 Video Capture (VICAP) block features a digital video
+ port (DVP, a parallel video interface) and six MIPI CSI-2 ports. It receives
+ the data from camera sensors, video decoders, or other companion ICs and
+ transfers it into system main memory by AXI bus and/or passes it to the image
+ signal processing (ISP) blocks.
