Now that the MT8183 encoder driver is ready, add its DT node. Also pull
the iommu and scp ones, which the encoder depends upon.
Please don't do that. Instead of pulling in other DT nodes, it would be handy to
get a reference of the series this is based on.
Let me try to hunt them down now :)
Sorry, I'm not sure to understand - do you mean each node should come
with its own patch? Or that all the code should be merged before
sending these nodes? The rest of this series should land into the
media tree soon, if you prefer I can resend this patch separately once
that happens.
What I'm talking about is the case when you send a series that's based on
another one and the latter is not yet accepted in Torvalds tree. In that case it
helps to point to the series you expect to be included as well.
In this case the SCP series was merged long time ago, but I missed the DTS
change. It would have been good if you would have added that information in your
series, instead of directly pulling in the SCP node.
For the iommu node: I understand that there was never a patch adding the node
(at least I wasn't able to find one). So I'd prefer to have it send as a
separate patch of this series.
Regarding this series now. If you want just resend the two DTS patches (iommu
and vcodec_enc) once the rest of this series got accpeted. If for any other
reason you have to send a v5, then feel free to include both in v5.
Hope I explained myself now :)
Regards,
Matthias
