Merge tag 'multiplatform-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull late ARM Exynos multiplatform changes from Arnd Bergmann:
"These continue the multiplatform support for exynos, adding support
for building most of the essential drivers (clocksource, clk, irqchip)
when combined with other platforms. As a result, it should become
really easy to add full multiplatform exynos support in 3.11, although
we don't yet enable it for 3.10.
The changes were not included in the earlier multiplatform series in
order to avoid clashes with the other Exynos updates.
This also includes work from Tomasz Figa to fix the pwm clocksource
code on Exynos, which is not strictly required for multiplatform, but
related to the other patches in this set and needed as a bug fix for
at least one board."
