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 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.

+description: |
+ ETHDR is designed for HDR video and graphics conversion in the external display path.
+ It handles multiple HDR input types and performs tone mapping, color space/color
+ format conversion, and then combine different layers, output the required HDR or
+ SDR signal to the subsequent display path. This engine is composed of two video
+ frontends, two graphic frontends, one video backend and a mixer. ETHDR has two
+ DMA function blocks, DS and ADL. These two function blocks read the pre-programmed
+ registers from DRAM and set them to HW in the v-blanking period.

+description: |
+ ETHDR is designed for HDR video and graphics conversion in the external display path.
+ It handles multiple HDR input types and performs tone mapping, color space/color
+ format conversion, and then combine different layers, output the required HDR or
+ SDR signal to the subsequent display path. This engine is composed of two video
+ frontends, two graphic frontends, one video backend and a mixer. ETHDR has two
+ DMA function blocks, DS and ADL. These two function blocks read the pre-programmed
+ registers from DRAM and set them to HW in the v-blanking period.

Add mmsys config API. The config API is used for config mmsys reg.
Some mmsys regs need to be setting according to the HW engine binding
to the mmsys simultaneously.

Add cmdq support for mtk-mmsys config API.
The mmsys config register settings need to take effect with the other
HW settings(like OVL_ADAPTOR...) at the same vblanking time.
If we use CPU to write the mmsys reg, we can't guarantee all the
settings can be written in the same vblanking time.
Cmdq is used for this purpose. We prepare all the related HW settings
in one cmdq packet. The first command in the packet is "wait stream done",
and then following with all the HW settings. After the cmdq packet is
flush to GCE HW. The GCE waits for the "stream done event" to coming
and then starts flushing all the HW settings. This can guarantee all
the settings flush in the same vblanking.

This is a preparation for adding support for mt8195 vdosys1 mutex.
The vdosys1 path component contains ovl_adaptor, merge5,
and dp_intf1. Ovl_adaptor is composed of several sub-elements,
so change it to support multi-bit control.

This is a preparation for adding support for mt8195 vdosys1 mutex.
The vdosys1 path component contains ovl_adaptor, merge5,
and dp_intf1. Ovl_adaptor is composed of several sub-elements,
so change it to support multi-bit control.

Add merge new advance config API. The original merge API is
mtk_ddp_comp_funcs function prototype. The API interface parameters
cannot be modified, so add a new config API for extension. This is
the preparation for ovl_adaptor merge control.

Add merge new advance config API. The original merge API is
mtk_ddp_comp_funcs function prototype. The API interface parameters
cannot be modified, so add a new config API for extension. This is
the preparation for ovl_adaptor merge control.

Add merge start/stop API for cmdq support. The ovl_adaptor merges
are configured with each drm plane update. Need to enable/disable
merge with cmdq making sure all the settings taken effect in the
same vblank.

Add merge async reset control in mtk_merge_stop. Async hw doesn't do self
reset on each sof signal(start of frame), so need to reset the async to
clear the hw status for the next merge start.

ETHDR is a part of ovl_adaptor.
ETHDR is designed for HDR video and graphics conversion in the external
display path. It handles multiple HDR input types and performs tone
mapping, color space/color format conversion, and then combine
different layers, output the required HDR or SDR signal to the
subsequent display path.

ETHDR is a part of ovl_adaptor.
ETHDR is designed for HDR video and graphics conversion in the external
display path. It handles multiple HDR input types and performs tone
mapping, color space/color format conversion, and then combine
different layers, output the required HDR or SDR signal to the
subsequent display path.

ETHDR is a part of ovl_adaptor.
ETHDR is designed for HDR video and graphics conversion in the external
display path. It handles multiple HDR input types and performs tone
mapping, color space/color format conversion, and then combine
different layers, output the required HDR or SDR signal to the
subsequent display path.

Add plane color encoding information for color space conversion.
It's a preparation for adding support for mt8195 ovl_adaptor mdp_rdma
csc control.

Add ovl_adaptor driver for MT8195.
Ovl_adaptor is an encapsulated module and designed for simplified
DRM control flow. This module is composed of 8 RDMAs, 4 MERGEs and
an ETHDR. Two RDMAs merge into one layer, so this module support 4
layers.

Add ovl_adaptor driver for MT8195.
Ovl_adaptor is an encapsulated module and designed for simplified
DRM control flow. This module is composed of 8 RDMAs, 4 MERGEs and
an ETHDR. Two RDMAs merge into one layer, so this module support 4
layers.

Add ovl_adaptor driver for MT8195.
Ovl_adaptor is an encapsulated module and designed for simplified
DRM control flow. This module is composed of 8 RDMAs, 4 MERGEs and
an ETHDR. Two RDMAs merge into one layer, so this module support 4
layers.

MT8195 have two mmsys. Modify drm for MT8195 multi-mmsys support.
The two mmsys (vdosys0 and vdosys1) will bring up two drm drivers,
only one drm driver register as the drm device.
Each drm driver binds its own component. The last bind drm driver
allocates and registers the drm device to drm core.
Each crtc path is created with the corresponding drm driver data.

* [PATCH v10 19/22] drm/mediatek: modify mediatek-drm for mt8195 multi mmsys support

MT8195 have two mmsys. Modify drm for MT8195 multi-mmsys support.
The two mmsys (vdosys0 and vdosys1) will bring up two drm drivers,
only one drm driver register as the drm device.
Each drm driver binds its own component. The last bind drm driver
allocates and registers the drm device to drm core.
Each crtc path is created with the corresponding drm driver data.

* [PATCH v10 19/22] drm/mediatek: modify mediatek-drm for mt8195 multi mmsys support

MT8195 have two mmsys. Modify drm for MT8195 multi-mmsys support.
The two mmsys (vdosys0 and vdosys1) will bring up two drm drivers,
only one drm driver register as the drm device.
Each drm driver binds its own component. The last bind drm driver
allocates and registers the drm device to drm core.
Each crtc path is created with the corresponding drm driver data.

I really do not understand how does i work. Could you give an example
of the i value for mt8173 crtc0, mt8173 crtc1, and all mt8195 crtcs.

After this patch, vdosys0 would not work. So set this to 1 in this
patch, and set this to 2 in the mt8195 vdosys1 patch.
