Add support for the Qualcomm PM8038 PMIC chip. The core driver
will communicate with the PMIC chip via the MSM SSBI bus.
Initial support is provided for: IRQ, GPIO, MPP, RTC, Power Key,
Misc, and Debug.

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.

Add two APIs, 1) set_current_limit API and 2) set_charging_by.
set_current_limit api is used for external control, such as for USB
driver to tell a charger driver the maximum current to draw.
set_charging_by is used to change the state of the charger.

Vmalloc will exit if the amount it needs to allocate is
greater than totalram_pages. Vmalloc cannot allocate
from the movable zone, so pages in the movable zone should
not be counted.
This change adds a new global variable: total_unmovable_pages.
It is calculated in init.c, based on totalram_pages minus
the pages in the movable zone. Vmalloc now looks at this new
global instead of totalram_pages.
total_unmovable_pages can be modified during memory_hotplug.
If the zone you are offlining/onlining is unmovable, then
you modify it similar to totalram_pages. If the zone is
movable, then no change is needed.

The previous algorithm requires that kpd_trigger_delay_us be set to
1/32 of the preferred trigger delay. The new algorithm allows setting
kpd_trigger_delay_us to the preferred trigger delay directly.
The actual delay can only be one of the eight levels: 2 sec, 1 sec,
1/2 sec, 1/4 sec, 1/8 sec, 1/16 sec, 1/32 sec, and 1/64 sec. The valid
range of kpd_trigger_delay_us is 1/64 second to 2 seconds. A value
within the valid range will be rounded down to the closest level. Any
value outside the valid range will be rejected.
Update board files for targets that use this driver accordingly.

Adding the L2 cycle counter in the default list of events
has the advantage that the user can do a :
perf stat -e l2-cycles -e cycles ls
and see the outputs for the L2 cycle counter and L1 cycle
counter separately. Previously, it was only accessible via
the raw code "rsfe".
This method also allows us to program the L2 cycle counter
only from one CPU.
The changes in this patch are used by the userspace perf
tool.

Fix this by adding a call to disable the input current limit and
