[PATCH v3 13/13] media: platform: mtk-mdp3: add support for parallel pipe to improve FPS
Moudy Ho
moudy.ho at mediatek.com
Fri Jan 13 01:03:21 PST 2023
In advanced chips, MDP3 has the ability to have multiple pipelines
process the same frame in parallel.
In order to implement it, multiple CMDQ clients and packets need to
be configured simultaneously.
