and in the NXP i.MX8MP have the same origin, and have slightly diverged

Debix model A with an IMX219 camera sensor (Raspberry Pi cam v2).

See individual patches for a detailed description of changes compared to

This should hopefully be the last version, I plan to send a pull request
in a few days, in time for v6.9.
