Besides my comment for PATCH 4/6, I have already reviewed the entire series,
and it looks good.
If adding new bindings for sdm845 needs a further review, can you separate out
just the phy patches from this series (patch 1, 2, 3 & 6), and re-send them.
We can ask Kishon if he can pull them in for this merge window.
Thanks.
