Subject: [PATCH v5 0/3] introduce more MDP3 components in mt8195

Changes since v4:
- Rebase on v6.6-rc1
- Organize identical hardware components into their respective files.

Hi,

The purpose of this patch is to separate the MDP3-related bindings from
the original mailing list mentioned below:
https://lore.kernel.org/all/[email protected]/
Those binding files describe additional components that
are present in the mt8195.

Moudy Ho (3):
dt-binding: mediatek: correct MDP3 node with generic names
dt-binding: mediatek: integrate MDP RDMA to one binding
dt-binding: mediatek: add MediaTek mt8195 MDP3 components

Subject: [PATCH v5 2/3] dt-binding: mediatek: integrate MDP RDMA to one binding

Due to the same hardware design, MDP RDMA needs to
be integrated into the same binding.
