You are mising sunxi-ng clock patches. PLL_VIDEO0 and PLL_VIDEO1 need fixes by setting minimum stable frequency. Please note that datasheet may have wrong information. That was obvious in H3 case and I had to check minimum stable PLL_VIDEO frequency in BSP driver. Without clock fixes, you might not see anything on the screen.
