Merge tag 'soc-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates (part 2) from Arnd Bergmann:
"These patches are all for Renesas shmobile, and depend on the earlier
pinctrl updates. Remarkably, this adds support for three new SoCs:
r8a73a4, r8a73a4 and r8a7778. The bulk of the code added for these is
for pinctrl (using the new subsystem) and for clocks (not yet using
the common clock subsystem). The latter will have to get converted in
one of the upcoming releases, but shmobile is not ready for that yet.
The series also contains Renesas shmobile board changes, adding one
board file for each of the three new SoCs. These boards are using a
mix of classic and device-tree based probing, as there is still a lot
of infrastructure in shmobile that has not been converted to DT yet.
Once those are resolved to the degree that no board specific setup
code is needed, they can get folded into the respective SoC setup files."
