OK .. so for framebuffer I took the imx53 driver and modified it to rockchip. From my understanding it does what I want. However, nothing happens. No error or anything.
After some tinkering I get it to start .. now I just need to fix the actual write to video chip.
I have a display now and it is really fast! However clipping doesn't work as it should. It doesn't crash but it makes graphics a bit blurry if active, and so is mouse pointer. There is no speed gain with clipping.

I really appreciate how the io mem is handled. At first I did it the hacky c way .. but then I looked into ipu.h from mx53 driver. It basically does everything automatically .
