Hi Nico, Thank you for your extensive answer. That helps a lot.
Regarding the registers description, maybe EDS or other documents have better situation? I have Braswell EDS so i can check it, but if you have any documents that describe display registers for Braswell, let me know which ID it is so I can get it myself. Thanks again.
