[PATCH v18 02/10] dt-bindings: arm: mediatek: mmsys: add mt8195 SoC binding

[jason-jh.lin]

In the SoC before, such as mt8173, it has 2 pipelines binding to one
mmsys with the same clock driver and the same power domain.

In mt8195, there are 4 pipelines binding to 4 different mmsys, such as
vdosys0, vdosys1, vppsys0 and vppsys1.
Each mmsys uses different clock drivers and different power domain.

Since each mmsys has its own mmio base address, they could be identified
by their different address during probe time.

Hello Rob, Krzysztof,

I found the dt-binding patches in this series never appeared in
devicetree-bindings patchwork and trigger the dt-binding check bot.

Do you know the reason for this?
Could you help me with this and let me know what should I do to solve

Hi,

All your emails end up regularly in my Gmail spam folder, similarly to
emails from some other Mediatek people (e.g. Rex-BC Chen), so maybe
that's the cause?

Why they end up in spam? I don't know, but it would be nice if you could
work on this with your IT department. I know that corporate environments
are tricky to change, but there is not much else to do. Google flags
your emails always as spam.

You can see in the headers two DMARC failures:
dmarc=fail (p=QUARANTINE sp=QUARANTINE dis=QUARANTINE)
header.from=mediatek.com

Spamming 27 recipients is maybe another reason...

Best regards,
Krzysztof

[PATCH v18 03/10] soc: mediatek: add mtk-mmsys support for mt8195 vdosys0

[jason-jh.lin]

1. Add mt8195 mmsys compatible for 2 vdosys.
2. Add io_start into each driver data of mt8195 vdosys.
3. Add get match data function to identify mmsys by io_start.
4. Add mt8195 routing table settings of vdosys0.

[PATCH v18 03/10] soc: mediatek: add mtk-mmsys support for mt8195 vdosys0

[jason-jh.lin]

1. Add mt8195 mmsys compatible for 2 vdosys.
2. Add io_start into each driver data of mt8195 vdosys.
3. Add get match data function to identify mmsys by io_start.
4. Add mt8195 routing table settings of vdosys0.

[PATCH v18 06/10] drm/mediatek: add MERGE support for mediatek-drm

[jason-jh.lin]

Add MERGE engine file:
MERGE module is used to merge two slice-per-line inputs
into one side-by-side output.

[PATCH v18 06/10] drm/mediatek: add MERGE support for mediatek-drm

[jason-jh.lin]

Add MERGE engine file:
MERGE module is used to merge two slice-per-line inputs
into one side-by-side output.

I can't reproduce this build warning in my platform, but I'd found the 
same warning fixed patch: 20210928154620.11181-4-cgzones@googlemail.com

It should not be fixed at this series. So I'll fixed this warning in
another fixed patch.

Oh, I forgot to replace the driver_data to match_data in mtk_drm_of_ids
table. I'll fix them at the next version.

I can't reproduce this build warning in my platform, but I'd found the 
same warning fixed patch: 20210928154620.11181-4-cgzones@googlemail.com

It should not be fixed at this series. So I'll fixed this warning in
another fixed patch.

Oh, I forgot to replace the driver_data to match_data in mtk_drm_of_ids
table. I'll fix them at the next version.

[PATCH v18 08/10] soc: mediatek: add DDP_DOMPONENT_DITHER0 enum for mt8195 vdosys0

[jason-jh.lin]

The mmsys routing table of mt8195 vdosys0 has 2 DITHER components,
so mmsys need to add DDP_COMPONENT_DITHER1 and change all usages of
DITHER enum form DDP_COMPONENT_DITHER to DDP_COMPONENT_DITHER0.

But its header need to keep DDP_COMPONENT_DITHER enum
until drm/mediatek also changed it.

Hello Jason,

IMO, it's strange.
In this case , I think you sholud squash [v18,08/10] and [v18,09/10].
Therefore, you don't need to describe this here.

[PATCH v18 09/10] drm/mediatek: add postfix 0 to DDP_COMPONENT_DITHER for mt8195 vdosys0

[jason-jh.lin]

Because mt8195 vdosys0 has 2 DITHER components,
so the postfix 0 need to be added to DDP_COMPONENT_DITHER.

Then DITHER enum will become:
DDP_COMPONENT_DITHER0 and DDP_COMPONENT_DITHER1.

[PATCH v18 10/10] soc: mediatek: remove DDP_DOMPONENT_DITHER enum

[jason-jh.lin]

After mmsys and drm change DITHER enum to DDP_COMPONENT_DITHER0,
mmsys header can remove the useless DDP_COMPONENT_DITHER enum.

You probably meant IS_ERR() instead of PTR_ERR().  But actually
platform_get_resource() does not return error pointers, it returns
NULL so the correct check is:
