Is this panel always present on the IDP board or is it an optional
addon, like the panels for all the RBn boards?

Hm.. generally we disable the GPU in the SoC DT, but that doesn't
seem to have happened here..
Thinking about it more, is disabling it here necessary? Does it
not fail gracefully?

Missed this.
I'd say, I don't see a reason to disable it at all. The GPU should be
working on sc7280 / qcm4290.

With GPU device node enabled, adreno_bind failure is seen as the
"speed_bin" was not populated on QCM6490 target which leads to display
bind failure.
Spoke with GPU team and on QCM6490 board, only CPU rendering is
supported for now and there is no plan to enable GPU rendering in near
future.
In this regard, what do you suggest
1) Disable GPU in QCM6490 DT (as per the current patch)
2) Disable GPU in the SoC DT, but enable it in other platform DTs. (This
will prompt change in all the dt's and we don't have all the devices to
test)
Please let me know your views on it.
Thanks,
Ritesh

Excuse me please. The GPU node for sc7280 already has speed_bin, which
points to qfprom + 0x1e9, bits 5 to 9.
Do you mean that qcm6490 uses different speed bin location? Or
different values for the speed bins?

This sounds like having the feature disabled for no particular reason.
Both the kernel and Mesa have supported the Adreno 635 for quite a
while.

The second option definitely follows what is present on other platforms.

Please enable the GPU instead.

Thanks for the help. After applying missing patches from series
https://patches.linaro.org/project/linux-arm-msm/cover/[email protected]/
in my local build, GPU is working fine. GPU disablement change is not
needed. I will send new version of patch removing GPU part and
addressing other review comments.
Thanks,
