Merge tag 'soc2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull arm-soc: soc specific changes (part 2) from Olof Johansson:
"This adds support for the spear13xx platform, which has first been
under review a long time ago and finally been completed after generic
spear work has gone into the clock, dt and pinctrl branches.
Also a number of updates for the samsung socs are part of this branch."
Fix up trivial conflicts in drivers/gpio/gpio-samsung.c that look much
worse than they are: the exonys5 init code was refactored in commit
fd454997d687 ("gpio: samsung: refactor gpiolib init for exynos4/5"), and
then commit f10590c9836c ("ARM: EXYNOS: add GPC4 bank instance") added a
new gpio chip define and did tiny updates to the init code.
So the conflict diff looks like hell, but it's actually a fairly simple
change.
