Hi Conor,

Mediatek's Media Data Path ver.3 (MDP3) is associated with MMSYS and
acts as an independent driver that operates between VDEC and DISP.
By controlling multiple components, it carries out tasks like
converting color formats, resizing, and applying specific Picture
Quality (PQ) effects.
The driver can be found at "driver/media/platform/mediatek/mdp3".
Since the same hardware components are configured in both MDP3 and
DISP, considering previous discussions, I attemped to integrate into a
single binding, named after the controlling user.

Sincerely,
Moudy
