These changes are all driver specific and cross over between arm-soc
contents and some other subsystem, in these cases cpufreq, crypto,
dma, pinctrl, mailbox and usb, and the subsystem owners agreed to
have these changes merged through arm-soc. As we proceed to untangle
the dependencies between platform code and driver code, the amount of
changes in this category is fortunately shrinking, for 3.11 we have
16 branches here and 101 non-merge changesets, the majority of which
are for the stedma40 dma engine driver used in the ux500 platform.
Cleaning up that code touches multiple subsystems, but gets rid
of the dependency in the end.
The mailbox code moved out from mach-omap2 to drivers/mailbox
is an intermediate step and is still omap specific at the moment.
Patches exist to generalize the subsystem and add other drivers
with the same API, but those did not make it for 3.11.
Conflicts:
* In cpu-db8500.c results from the removal of the u8500_of_init_devices
function in combination with the split of u8500_auxdata_lookup.
* In arch/arm/mach-omap2/devices.c, the includes got reshuffled.
we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h.

in this time, usually in order to atomically move over a driver from
using hardcoded data to DT probing.
A number of platforms change their DT files to use the C preprocessor,
which is causing a bit of churn, but that is hopefully only this once.
There are a few conflicts with the other branches unfortunately:
* in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
from multiple branches. Need to be careful to have the right
set of closing braces as git gets this one wrong.
* In kirkwood.dtsi, one 'ranges' line got split into two lines, while
another line got added. Order of the lines does not matter.
* in sama5d3.dtsi, some cleanup was merged the wrong way, causing
a bogus conflict. We want the 'dmas' and 'dma-names' properties
to get added here.
* Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
* Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

This change makes the rtc on the exynos5250 and 5440 disabled by
default to match exynos4.
Ever since the common clock framework came in, exynos5250 boards
have dumped lots of warnings in the boot log. It turns out that
we don't see those on exynos4 since the rtc is disabled by default.
While we need to get to the bottom of the problems with the RTC,
it still makes sense to have the default state of the RTC on exynos
boards match.
For the record, warnings look like this:
