Merge tag 'armsoc-for-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson:
"A collection of fixes this week:
- A set of clock fixes for shmobile platforms
- A fix for tegra that moves serial port labels to be per board.
We're choosing to merge this for 3.18 because the labels will start
being parsed in 3.19, and without this change serial port numbers
that used to be stable since the dawn of time will change numbers.
- A few other DT tweaks for Tegra.
- A fix for multi_v7_defconfig that makes it stop spewing cpufreq
errors on Arndale (Exynos)"

+Additionally to the properties specified in the above standards a host bridge
+driver implementation may support the following properties:
+
+- linux,pci-domain:
+ If present this property assigns a fixed PCI domain number to a host bridge,
+ otherwise an unstable (across boots) unique number will be assigned.
+ It is required to either not set this property at all or set it for all
+ host bridges in the system, otherwise potentially conflicting domain numbers
+ may be assigned to root buses behind different host bridges. The domain
+ number for each host bridge in the system must be unique.
