USB device can specify remote wakeup capability in the configuration
descriptor. Host may select remote wakeup feature before suspending
the device. Remote wakeup capability is disabled by default in
android gadget. Provide sysfs file for enabling remote wakeup capability.
User space can enable/disable this capability based on the selected
composition. This will also allow testing suspend/resume chapter 9 tests
with remote wakeup enabled.

As discussed previously, there's the need on some platforms to run some
parts of clk_enable() in contexts which can schedule. The solution
which was agreed upon was to provide clk_prepare() and clk_unprepare()
to contain this parts, while clk_enable() and clk_disable() perform
the atomic part.
This patch provides a common definition for clk_prepare() and
clk_unprepare() in linux/clk.h, and provides an upgrade path for
existing implementation and drivers: drivers can start using
clk_prepare() and clk_unprepare() once this patch is merged without
having to wait for platform support. Platforms can then start to
provide these additional functions.
Eventually, HAVE_CLK_PREPARE will be removed from the kernel, and
everyone will have to provide these new APIs.

USB PHY takes TCXO clock as input and using the PHY internal PLL,
gets the 480MHz clock for USB operations. While USB PHY is suspended,
the TCXO clock can be turned off.
On 8960 target, mandating that TCXO clock users must need to vote for
TCXO and if all the users vote for TCXO clock-off, then MSM can switch to
lower power clock and can run.

FM configuration failure is due to two issues. Since the calibration
will take around 6 seconds to complete, any commands sent to SOC
during that time will fail.Added a state machine to prevent the
execution of another command while FM calibration is in progress.
The other issues is with the Get tuner command.FM kernel driver is
sending the Rx specific command to get the Tx configuration.
Send the proper command to get the TX configuration parameters.

Currently, Ion registers all debugfs entries for clients
via pid. If there are multiple kernel clients, this means
the debugfs entry only gets created for the first one. Fix
this by creating debugfs entries by name always. When
creating user clients, specify the name via the pid.

Some hangs are fooling the postmortem dump code into
running off the end of a buffer. Fix this by making
its bounds check logic work better by reusing the
logic from kgsl_find_region().
