- remove MTK_MMSYS 64 bit dependency
- add ethdr.yaml back and fix dt_schema check fail

Resend v13
- add related maintainer in maillist

Changes in v13:
- fix reviewer comment in v12
  - fix rdma dt-binding format
  - fix dts node naming
- fix 32 bit build error
  - modify 64bit dependency for mtk-mmsys
- rebase to vdosys0 series v16. (ref [5])

Changes in v12:
- fix reviewer comment in v11
  - modify mbox index
  - refine dma dev for ovl_adaptor sub driver

Changes in v11:
- remove ethdr vblank spin lock
- refine ovl_adaptor print message

Changes in v10:
- refine ethdr reset control using devm_reset_control_array_get_optional_exclusive
- fix ovl_adaptor mtk_ovl_adaptor_clk_enable error handle issue

Changes in v9:
- rebase on kernel-5.16-rc1
- rebase on vdosys0 series v13. (ref [5])
- fix ovl_adaptor sub driver is brought up unintentionally
- fix clang build test fail- duplicate ethdr/mdp_rdma init_module/cleanup_module symbol issue 

Changes in v8:
- separate merge async reset to new patch.
- separate drm ovl_adaptor sub driver to new patch.
- fix reviewer comment in v7.

Changes in v7:
- rebase on vdosys0 series v12 (ref[5])
- add dma description in ethdr binding document.
- refine vdosys1 bit definition of mmsys routing table.
- separate merge modification into 3 pathces.
- separate mutex modification into 2 patches.
- add plane color coding for mdp_rdma csc.
- move mdp_rdma pm control to ovl_adaptor.
- fix reviewer comment in v6.

Changes in v6:
- rebase on kernel-5.15-rc1.
- change mbox label to gce0 for dts node of vdosys1.
- modify mmsys reset num for mt8195.
- rebase on vdosys0 series v10. (ref [5])
- use drm to bring up ovl_adaptor driver.
- move drm iommu/mutex check from kms init to drm bind.
- modify rdma binding doc location. (Documentation/devicetree/bindings/arm/)
- modify for reviewer's comment in v5.

Changes in v5:
- add mmsys reset controller reference.

Changes in v4:
- use merge common driver for merge1~4.
- refine ovl_adaptor rdma driver.
- use ovl_adaptor ddp_comp function instead of ethdr.
- modify for reviewer's comment in v3.

Changes in v3:
- modify for reviewer's comment in v2.
- add vdosys1 2 pixels align limit.
- add mixer odd offset support.

Changes in v2:
- Merge PSEUDO_OVL and ETHDR into one DRM component.
