Pull ARM SoC power management and clock changes from Olof Johansson:
"This branch contains a largeish set of updates of power management and
clock setup. The bulk of it is for OMAP/AM33xx platforms, but also a
few around hotplug/suspend/resume on Exynos.
It includes a split-up of some of the OMAP clock data into separate
files which adds to the diffstat, but gross delta is fairly reasonable."

Pull staging driver tree merge from Greg Kroah-Hartman:
"Here's the big staging tree merge for 3.8-rc1
There's a lot of patches in here, the majority being the comedi
rework/cleanup that has been ongoing and is causing a huge reduction
in overall code size, which is amazing to watch. We also removed some
older drivers (telephony and rts_pstor), and added a new one (fwserial
which also came in through the tty tree due to tty api changes, take
that one if you get merge conflicts.)
The iio and ipack drivers are moving out of the staging area into
their own part of the kernel as they have been cleaned up sufficiently
and are working well.
Overall, again a reduction of code:

This prevents hwmod _enable_clocks...omap2_dflt_clk_enable path
from enabling modulemode inside CLKCTRL using its clk->enable_reg
field. Instead is left to _omap4_enable_module though soc_ops, as
the one in charge of this setting.
According to comments received[1] for related patches the idea is
to get rid of leaf clocks in future. So remove these two while at it.

Use runtime PM functionality interfaced with hwmod enable/idle
functions, to replace direct clock operations and sysconfig
handling.
Due to reset sequence, pm_runtime_[get|put]_sync must be used, to
avoid possible operations with the module under reset. Because of
this and given that the driver uses spin_locks to protect their
critical sections, we must use pm_runtime_irq_safe in order for the
runtime ops to be happy, otherwise might_sleep_if checks in runtime
framework will complain.
The remaining pm_runtime out of iommu_enable and iommu_disable
corresponds to paths that can be accessed through debugfs, some of
them doesn't work if the module is not enabled first, but in future
if the mmu is idled withouth freeing, these are needed to debug.

Use hwmod data and device attributes to build and register an
omap device for iommu driver.
- Update the naming convention in isp module.
- Remove unneeded check for number of resources, as this is now
handled by omap_device and prevents driver from loading.
- Now unused, remove platform device and resource data, handling
of sysconfig register for softreset purposes, use default
latency structure.
- Use hwmod API for reset handling.

Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.
Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.
So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.
The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.
Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.
Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.
Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.
Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

When booting with DT the OF core can fill up the resources provided within
the DT blob.
The current way of handling the DT boot prevents us from removing hwmod data
for platforms only suppose to boot with DT (OMAP5 for example) since we need
to keep the whole hwmod database intact in order to have more resources in
hwmod than in DT (to be able to append the DMA resource from hwmod).
To fix this issue we just examine the OF provided resources:
If we do not have resources we use hwmod to fill them.
If we have resources we check if we already able to recive DMA resource, if
no we only append the DMA resurce from hwmod to the OF provided ones.
In this way we can start removing hwmod data for devices which have their
resources correctly configured in DT without regressions.

OMAP4 has module specific context lost registers which makes it now
possible to have module level context loss count, instead of relying
on the powerdomain level context count.
Add 2 private hwmod api's to update/clear the hwmod/module specific
context lost counters/register.
Update the module specific context_lost_counter and clear the hardware
bits just after enabling the module.
omap_hwmod_get_context_loss_count() now returns the hwmod context loss
count them on platforms where they exist (OMAP4), else fall back on
the pwrdm level counters for older platforms.

Commit 97ee9f01 (ARM: OMAP: fix the ads7846 init code) have enabled the
pendown GPIO debounce time setting by the below sequence:
gpio_request_one()
gpio_set_debounce()
gpio_free()
It also revealed a bug in the OMAP GPIO handling code which prevented
the GPIO debounce clock to be disabled and CORE transition to low power
states.
Commit c9c55d9 (gpio/omap: fix off-mode bug: clear debounce settings on
free/reset) fixes the OMAP GPIO handling code by making sure that the
GPIO debounce clock gets disabled if no GPIO is requested from current
bank.
While fixing the OMAP GPIO handling code (in the right way), the above
commit makes the gpio_request->set_debounce->free sequence invalid as
after freeing the GPIO, the debounce settings are lost.
Fix the debounce settings by moving the debounce initialization to the
actual GPIO requesting code - the ads7846 driver.

CONFIG_OMAP_32K_TIMER is kind of standing on the single zImage way.
Make OMAP2+ timer code independant from the CONFIG_OMAP_32K_TIMER
setting.
To remove the dependancy, several conversions/additions had to be done:
1) Timer initialization functions are named by the platform
name and the clock source in use.
This also makes it possible to define and use the GPTIMER as the
clock source instead of the 32K timer on platforms that do not have
the 32K timer ip block or the 32K timer is not wired on the board.
Currently, the the timer is chosen in the machine_desc structure on
per board basis. Later, DT should be used to choose the timer.
2) Settings under the CONFIG_OMAP_32K_TIMER option are used as defaults
and those under !CONFIG_OMAP_32K_TIMER are removed.
This removes the CONFIG_OMAP_32K_TIMER on OMAP2+ timer code.
3) Since we have all the timers defined inside machine_desc structure
and we no longer need the fallback to gp_timer clock source in case
32k_timer clock source is unavailable (namely on AM33xx), we no
longer need the #ifdef around omap2_sync32k_clocksource_init()
function. Remove the #ifdef CONFIG_OMAP_32K_TIMER around the
omap2_sync32k_clocksource_init() function.

Looks like the iommu framework does not have generic functions
exported for all the needs yet. The hardware specific functions
are defined in files like intel-iommu.h and amd-iommu.h. Follow
the same standard for omap-iommu.h.
This is needed because we are removing plat and mach includes
for ARM common zImage support. Further work should continue
in the iommu framework context as only pure platform data will
be communicated from arch/arm/*omap*/* code to the iommu
framework.
