Subject: [PATCH v5 3/3] media: platform: mtk-mdp3: Add Mediatek MDP3 driver
This patch adds driver for Media Data Path 3 (MDP3).
Each modules' related operation control is sited in mtk-mdp3-comp.c
Each modules' register table is defined in file with "mdp_reg_"
and "mmsys_" prefix
GCE related API, operation control sited in mtk-mdp3-cmdq.c
V4L2 m2m device functions are implemented in mtk-mdp3-m2m.c
Probe, power, suspend/resume, system level functions are defined in
mtk-mdp3-core.c
