Subject: [PATCH 2/3] drm/msm/dpu: add support for MDP_TOP blackhole

From: Dmitry Baryshkov <[email protected]>

On sm8450 a register block was removed from MDP TOP. Accessing it during
snapshotting results in NoC errors / immediate reboot. Skip accessing
these registers during snapshot.

Subject: [PATCH 3/3] drm/msm/dpu: Introduce SC8280XP

The Qualcomm SC8280XP platform contains DPU version 8.0.0, has 9
interfaces, 2 DSI controllers and 4 DisplayPort controllers. Extend the
necessary definitions and describe the DPU in the SC8280XP.

Note that MSM_DP_CONTROLLER_3 is also defined in the DP series and as such a
trivial conflict will occur when merging the latter of the two series.

qcom prefix is needed (also when file is in msm subdir)

The file name should be based on compatible, so "qcom,sc8280xp-mdss.yaml"

s/Device tree bindings//
so just:

SC8280XP MSM Mobile Display Subsystem (MDSS) that encapsulates
sub-blocks like DPU display controller, DSI and DP interfaces etc.

You do not need reg names for one item, especially if the name is kind
of obvious... unless you re-use existing driver which needs it? Then
maybe let's change the driver to take first element?

I see other DPU bindings also specify both as "true". Why not a fixed
number (const)?

No need for minItems in such case.

additionalProperties:false on this level

which will point to missing properties (e.g. opp-table)

OK, I see the driver expects this. It seems it is legacy from
87729e2a7871 ("drm/msm: unify MDSS drivers") times. So it could be
changed to grab first element always (older MDSS with three reg items
still has mdss_phys at first item).

I'll fix existing bindings which have similar issue.

Hm, I think Dmitry is already working on this:
https://lore.kernel.org/all/[email protected]/
so your patches should be on top of his.

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'

This check can fail if there are any dependencies. The base for a patch

If you already ran 'make dt_binding_check' and didn't see the above

pip3 install dtschema --upgrade
