Just an update from my side about merging the platform code: the
submission looks mostly sensible to me, but as long as the clk and irqchip
drivers have not finished the review, I cannot take this through the soc
tree. We could consider merging the platform code without those two
drivers, but that seems pointless because it will not boot.

What is the reason you don't include a .dtsi file in this series? Usually
there should be at least one board and the description of the SoC itself.
Again, without those I'm not sure it's worth merging.

For the timing, we are getting close to the 5.19 merge window that
starts once v5.18 is out, and I don't expect that all the above will
be resolved in time, so it looks we will have to defer it by one more
release to 5.20.
