Convert the HSMMC driver to use the runtime PM layer. A notable
aspect of this is that the use of the dev_attr data from the
omap_hwmod allows the redaction of all of the integration-specific
hacks inside this driver. Regulator control has not yet been
converted; the driver still uses the platform_data set_power hook.
In converting to runtime PM layer, the clock frameworks is no longer
used for fclk and iclk. Instead, the runtime PM get and put functions
are used. These result in calls into the OMAP runtime PM core which
internally uses the omap_device API to disable/re-enable the device.
(Note that the 2430 debounce clock is not currently handled here,
only the fclk and iclk are managed.)
Based on an initial conversion of this driver to use omap_device by
by Paul Walmsely: http://marc.info/?l=linux-omap&m=124419789124570&w=2
and then converted to use runtime PM API instead of omap_device API.
The omap_hsmmc driver has some hacks in this version to compensate for
the fact that the main runtime PM core prevents runtime transitions
during suspend. This prevens us from using common hooks for runtime
PM and static PM. Current workaround is to hack in some extra put/get
calls in the suspend/resume path while this issue is being discussed
on linux-pm.

Split OMAP-common MMC device registration into OMAP1 and OMAP2

Convert PM operations to use dev_pm_ops. This will facilitate
the runtime PM coversion which will add to dev_pm_ops hooks.
Note that dev_pm_ops version of the suspend hook no longer takes a
'state' argument. However, the MMC core function mmc_suspend_host()
still takes a 'state' argument, but it is unused, so a dummy
state variable was created to pass to the MMC core.
In the future, the MMC core should be converted to drop this
state argument and the rest of the MMC drivers could be easily
converted to dev_pm_ops as well.

The integration data is so similar between 2430 and 34xx in this
case that these entries could almost be shared; that is probably worth
investigating.

As part of the runtime PM support, bus-level code can automatically
handle the enable/idle for each omap_device. There are, however, some
special cases where we don't want the bus-level layer to handle this,
and instead handle it manually.
Specific use cases are for omap_devices that are controlled
inside the idle path (like UART.)

Hook into the platform bus methods for suspend and resume and
use the omap_device API to automatically idle and enable the
device on suspend and resume.
This allows device drivers to get rid of direct management of their
clocks in their suspend/resume paths, and let omap_device do it for
them.
We currently use the _noirq (late suspend, early resume) versions of
the suspend/resume methods to ensure that the device is not disabled
too early for any drivers also using the _noirq methods.
NOTE: only works for devices with omap_hwmod support.

Implement the new runtime PM framework as a thin layer on top of the
omap_device API. Since we don't have an OMAP-specific bus, override
the runtime PM hooks for the platform_bus for the OMAP specific
implementation.
While the runtime PM API has three main states (idle, suspend, resume)
This version treats idle and suspend the same way by implementing both
on top of omap_device_disable(), which follows closely with how driver
are currently using clock enable/disable calls. Longer-termm
pm_runtime_idle() could take other constraints into consideration to
make the decision, but the current
Device driver ->runtime_suspend() hooks are called just before the
device is disabled (via omap_device_idle()), and device driver
->runtime_resume() hooks are called just after device has been
enabled (via omap_device_enable().)

When runtime PM for platform_bus was added, it allowed for platforms
to customize the runtime PM methods since they are defined as weak
symbols.
This patch allows platforms to also extend the system PM methods with
custom hooks so runtime PM and system PM extensions can be managed
together by custom platform-specific code.

Dma channels are allocated in musb_gadget_enable function.
Mentor has only 8 dma channels against 31 endpoints.If there are
multiple gadgets(g_multi) using multiple endpoints enable the endpoints
but not doing the data trasnfers,then other endpoints endup using PIO mode.
The effective utilization of DMA channels will be done by allocating
the dma channels during data transfer request and releasing when the
request completes.

The current DMA code is expected the DMA request line to start at 1,
whereas the information in the HW data based start at 0.
Add the offset to the DMA request lines for the moment.
In the future, the DMA code might be revisited in order to take

complete framework is binded with CONIFG_PM. But if clocks
are disabled by any other mneans from hwmod_idle or

shared interrupt handler for which the mechanism is currenlty
