I've sent a general Excel-Document a while ago, can't remember if it was included there already.
Otherwise, doesn't the datasheet have that included? If not, I'll simply ask them :)

Hi,
it seems there's no driver yet for Linux, but hopefully, it shouldn't be too hard writing one (as it basically only needs to send MIPI commands).
Solomon Systech has created an Excel-Sheet for us which has the commands included to initialize the chip and set it to 1280x720 rotated. It is attached.
I guess the best way is to create a Display driver, so that Linux thinks the chip is a standard monitor supporting multiple resolutions.
It would be great if we include many standard resolutions (like 800x480, 800x600, 640x480, 1024x600, etc.) which will be reported as standard modes to Linux.
We'll need similar tables from Solomon for each scaled mode we want to support, also scaler registers settings and coefficient tables. Or some guide how to calculate those values, even though the datasheet explains how the hardware works, it's not obvious how to generate filter tables without knowing FIR filter theory.
