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

In reply to Dikshita Agarwal

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 Matthias,

Quoted 2 lines · Matthias Kaehlcke

From a quick glance this looks extremely similar to the venus binding for sc7180. Is there really a good reason for a separate binding?

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

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?

iface
vcodec_core
vcodec_bus
