Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM DT updates from Olof Johansson:
"As usual, this is the massive branch we have for each release. Lots
of various updates and additions of hardware descriptions on existing
hardware, as well as the usual additions of new boards and SoCs.
This is also the first release where we've started mixing 64- and
32-bit DT updates in one branch.
(Specific details on what's actually here and new is pretty easy to
tell from the diffstat, so there's little point in duplicating listing
it here)"
