This is a rather large set of patches for device drivers that for one
reason or another the subsystem maintainer preferred to get merged
through the arm-soc tree. There are both new drivers as well as
existing drivers that are getting converted from platform-specific
code into standalone drivers using the appropriate subsystem
specific interfaces.
In particular, we can now have pinctrl, clk, clksource and irqchip
drivers in one file per driver, without the need to call into
platform specific interface, or to get called from platform specific
code, as long as all information about the hardware is provided
through a device tree.
Most of the drivers we touch this time are for clocksource. Since
now most of them are part of drivers/clocksource, I expect that we
won't have to touch these again from arm-soc and can let the
clocksource maintainers take care of these in the future.
Another larger part of this series is specific to the exynos platform,
which is seeing some significant effort in upstreaming and
modernization of its device drivers this time around, which
unfortunately is also the cause for the churn and a lot of the
merge conflicts.
There is one new subsystem that gets merged as part of this series:
the reset controller interface, which is a very simple interface
for taking devices on the SoC out of reset or back into reset.
Patches to use this interface on i.MX follow later in this merge
window, and we are going to have other platforms (at least tegra
and sirf) get converted in 3.11. This will let us get rid of
platform specific callbacks in a number of platform independent
device drivers.
