I have a GLCD display which is 128x64, similar to others. I would like to help to merge my LM6023 (using S1D15300 IC) repo to yours, may I know any guide / reference for adding a new.

Or just let me know if I provide anything could assist you to add it quickly, such as the initial commands, power control commands, etc.
