The hardware path of vdosys1 with DPTx output need to go through by several modules, such as, OVL_ADAPTOR and MERGE.
Add DRM and these modules support by the patches below:
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.
- Add mmsys config API for vdosys1 hardware setting.
- Add mmsys reset control using linux reset framework.
