My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):
yamllint warnings/errors:
dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/media/qcom,sc7280-venus.example.dts:19:18: fatal error: dt-bindings/clock/qcom,videocc-sc7280.h: No such file or directory

make: *** [Makefile:1414: dt_binding_check] Error 2
See https://patchwork.ozlabs.org/patch/1470241
This check can fail if there are any dependencies. The base for a patch
series is generally the most recent rc1.
If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:
pip3 install dtschema --upgrade
Please check and re-submit.
From a quick glance this looks extremely similar to the venus binding
for sc7180. Is there really a good reason for a separate binding?

Hi Rob,
Thanks for your comment.
Actually, this change depends on
https://patchwork.kernel.org/project/linux-arm-msm/list/?series=473809
which adds the file dt-bindings/clock/qcom,videocc-sc7280.h (v2 5/6)
Missed adding the dependency in commit text.
Thanks,
Dikshita

Maybe we can mention that this is Venus Iris2 IP?

The sm8250 (the same Iris2 IP) has one more MX power domain, I guess we
should have it here too?

I'd suggest following names:
core
bus
iface
vcodec_core
vcodec_bus

Do we have sc7280 interconnect binding somewhere?

The Venus IP is different (newer) for sc7280 (Iris2 vs AR50), and I
think it is clearer if we have separate yaml for it.
