Looks like a good objective. The i.MX display pipeline is reasonably
reverse engineered to have a full open open source experience.

Reading this list I guess you'll need a few things before you start:
1. Check is the i.MX7 fits the powerprofile
2. Find a reference design. NDA free
3. Check if the i.MX7 has all required outputs. Or needs converter IC's
