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