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 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. - Add mmsys config API for vdosys1 hardware setting. - Add mmsys reset control using linux reset framework.
