Linus Torvalds bb9055b274 ARM: late Exynos multiplatform changes 
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.
