Subject: [PATCH v2 0/2] MediaTek MDP3: use devicetree to retrieve SCP

Changes in v2:
 - Rebased over media_stage master as of 05/10/2023
 - Reworked description of mediatek,scp property in bindings
   - Dropped Conor's and Chen-Yu's R-b tags from bindings patch due
     to the description rework.

Especially now that Multi-Core SCP support has landed, it makes sense to
retrieve the SCP handle by using the "mediatek,scp" property (as already
done in MediaTek VCODEC), both to select one specific SCP core for MDP3
and to avoid walking the parent node to find a SCP node.

  media: dt-bindings: mediatek: Add phandle to mediatek,scp on MDP3 RDMA
  media: platform: mtk-mdp3: Use devicetree phandle to retrieve SCP
