[PATCH v7 12/12] media: platform: mtk-mdp3: add support for parallel pipe to improve FPS

From: Moudy Ho
Date: Thu Oct 12 2023 - 05:12:47 EST

In some chips, MDP3 has the ability to utilize two pipelines to
parallelly process a single frame.
To enable this feature, multiple CMDQ clients and packets need to
be configured at the same time.
