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.

* [PATCH 2/3] drm/msm/dpu: add support for MDP_TOP blackhole
@ 2022-08-11 4:01 ` Bjorn Andersson

From: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
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.

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.

* [PATCH 3/3] drm/msm/dpu: Introduce SC8280XP
@ 2022-08-11 4:01 ` Bjorn Andersson

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.
Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>

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"

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?

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).

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).

Hm, I think Dmitry is already working on this:
https://lore.kernel.org/all/20220710090040.35193-5-dmitry.baryshkov@linaro.org/
so your patches should be on top of his.
