Linus Torvalds 11801e9de2 ARM: soc: soc-specific updates 
Most notable here is probably the addition of basic support for the
 BCM2835, an SoC used in some of the Roku 2 players as well as the
 much-hyped Raspberry Pi, cleaned up and contributed by Stephen
 Warren. It's still early days on mainline support, with just the
 basics working. But it has to start somewhere!
 
 Beyond that there's some conversions of clock infrastructure on tegra
 to common clock, misc updates for several other platforms, and OMAP
 now has its own bus (under drivers/bus) to manage its devices through.
 
 This branch adds two new directories outside of arch/arm:
 drivers/irqchip for new irq controllers, and drivers/bus for the above
 OMAP bus. It's expected that some of the other platforms will migrate
 parts of their platforms to those directories over time as well.

 "Most notable here is probably the addition of basic support for the

Fix up trivial conflicts with the clk infrastructure changes.
