It's been just three days ago and I just didn't find time yet to review 
them. I would like to be able to review all the patches straight after 
them being posted, but unfortunately that's not the only thing I have to do.

Anyway, a common practice in open source world is to let the patches 
wait on the mailing lists for two weeks for people to find some time to 
review them and only then apply. There might be people that don't work 
full time on this area, but still would be interested to do a review in 
some free time.

Also, neither version of this series have been posted to 
linux-samsung-soc mailing list, which is also a key to have a broader 
review. Note that this ML is listed in MAINTAINERS file for all kernel 
files with "exynos" in name.

Yes, they are, but for other platforms not this particular instance.

Any new DT bindings introduced are needed to have an ACK from one of DT 
maintainers to be merged, unless you can't get any reply from any of 
them for a longer time, usually 3 weeks from posting the series to be 
applied.

Of course standard pinging rules apply, so you should ping DT 
maintainers first before applying such series.

I don't think there is any need to hurry up with this particular series 
for this release. I'd recommend sending a pull request with remaining 
patches separately, as the supernode is not required to make anything 
work, rather than being just a refactor.
