My sabge understanding on today:
VOP(VOP2) is the DMA core for fetching data from AXI bus mapped frame buffer to display device (LCD panel, LVDS, MIPI, eDP, HDMI, TV set). There is no another way to work with display device.
There are both VOPb and VOPl are need in Linux. There is no one display video output each If one of them not init.
In general case, no more 2 display device are possible. In the custom case MIPI configuration, there are 3 display device are possible.
