[PATCH v1 2/9] drm/msm/dpu: Refactor sc7280_pp location

[Robert Foss]

The sc7280_pp declaration is not located by the other _pp
declarations, but rather hidden around the _merge_3d
declarations. Let's fix this to avoid confusion.

[PATCH v1 9/9] arm64: dts: qcom: sm8350-hdk: Enable lt9611uxc dsi-hdmi bridge

[Robert Foss]

The sm8350-hdk ships with the LT9611 UXC DSI/HDMI bridge chip.

In order to toggle the board to enable the HDMI output,
switch #7 & #8 on the rightmost multi-switch package have
to be toggled to On.

BTW: you probably also have to update the msm_mdss_enable() function 
with the 8350-specific code.

The UNIFIED_DSPP_FLUSH is not merged. Could you please change this to 
BIT(DPU_CTL_SPLIT_DISPLAY) | CTL_SC7280_MASK (for first two CTLs) and 
just CTL_SC7280_MASK for the rest of them?

For mdss changes you can depend on [1], I plan to merge this patch in 
this window.

[1] https://patchwork.freedesktop.org/patch/489578/?series=105162&rev=1

Also with the mdss changes, it would be good to split this patch into 
dpu and mdss parts.

You also need amend all the interconnects references with the additional
tag cell.

That seems a little bit aggressive, is the opp-based voting from within
the mdss/dpu not sufficient?

If you prefix the label for the dsi controller and phy with mdss_ they
sort nicely together with the other display nodes.

Since this doesn't look like a default setup, it would probably make 
sense to move this to new sm8350-hdk-hdmi.dts with the comment regarding 
necessary switch changes at the top of the file.

Please keep status last. (Yes I see that it goes against the convention
in this file, so let's update that at some point as well)

pinctrl state nodes should be suffixed with "-state".

And you can lump the two pins into a single -state, with rst-pins and
irq-pins as subnodes, defining the two pins.

Just "phy". I think Dmitry was renaming all of these.

Generic node names, so hdmi-connector or just connector.

Node names should be generic.

Missing suffix 'state'.

Does not look like you tested the DTS against bindings. Please run `make
dtbs_check` (see Documentation/devicetree/bindings/writing-schema.rst
for instructions).

Rebase your changes on last linux-next.

Please excuse me here. I checked the Lantronix site. It clearly names 
'Optional Display/Expansion board mates to DSI connectors'. So, you were 
correct, the HDMI should be in the base setup, while DSI panel should 
come as the extending DT file.

4096 is what I'm seeing in the downstream dts, except for the
wb-linewidth-linear property which is 5120.

So I would think 4096 is the correct value, what do you think?
