MediaTek IOMMU has already added the device_link between the consumer
and smi-larb device. If the vcodec device call the pm_runtime_get_sync,
the smi-larb's pm_runtime_get_sync also be called automatically.

You can't delete the return; here, otherwise vcodec_clk will be turned
off immediately after they are turned on.

Thanks very much for your review.

Sorry for this. You are quite right.

I checked this, it was introduced in v4 when I rebase the code. I will
fix it in next time.

Please also make sure that you add all maintainers. I realized that at least for
the media/platform drivers we miss the maintainer and the corresponding mailing
list.
This is especially important in this series, as it spans several subsystems.

Thanks for hint. I only added the file maintainer here. I will add
linux-media in next version.

By the way, this patchset cross several trees, then which tree should it
go through. Do you have some suggestion?

That's a good question. I think the media tree would be a good candidate, as it
has the biggest bunch of patches. But that would mean that Joerg is fine that.
The DTS part could still go through my tree.

Regards,
Matthias
