These are cleanups and smaller changes that either depend on earlier
feature branches or came in late during the development cycle.
We normally try to get all cleanups early, so these are the exceptions:
- A follow-up on the clocksource reworks, hopefully the last time
we need to merge clocksource subsystem changes through arm-soc.
A first set of patches was part of the original 3.10 arm-soc cleanup
series because of interdependencies with timer drivers now moved out
of arch/arm.
- Migrating the SPEAr13xx platform away from using auxdata for DMA
channel descriptions towards using information in device tree,
based on the earlier SPEAr multiplatform series
- A few follow-ups on the Atmel SAMA5 support and other changes
for Atmel at91 based on the larger at91 reworks.
- Moving the armada irqchip implementation to drivers/irqchip
- Several OMAP cleanups following up on the larger series already
merged in 3.10.
