Why is dsi_div value computed as bpp / lanes? #68

Any idea why is dsi_div value is depends on bpp and lanes. since dsi_div indeed compute the pll_rate making default to 4 can't work in all the LCD panels with different lane size?

No clue, this whole video driver is a mess made by the hardware vendor. Best do not look at it unless you have to. This is just an import of the BSP as provided - if you need specific advice either get in contact with the author of that particular driver or get involved with the https://linux-sunxi.org/ community.
