ulpi_read() relies on jiffies to calculate the timeout
for read operation on phy register. Calling ulpi_read()
with interrupts disabled, freezes jiffies on local processor.
In case of phy lockup this results in infinite loop leading
to watchdog reset. Use loop counter for timeout instead of
jiffies for read operation to avoid watchdog reset.

Several changes are pending to be pulled in which are
not compatible with our changes. Specifically, a new
field to the allocation ioctl is added and the ioctl
numbers for cache flushing need to be changed.
Add these changes now until full changes can be pulled
in the future.

An earlier commit(ec5b2f)increased the number of reserved fields
in the kernel standard fb.h header changing the struct size.
This caused issues with userland applications using the corresponding
bionic header. This patch revert the earlier increas in size
and makes corresponding adjustments to the reserved field usage.
A follow up patch will remove usage of reserved fields entirely.
During UVLO events the charger hardware may lock up
if it is in hardware clock switching mode.
To fix this add a battery alarm with a lower threshold
that disables hardware clock switching.
When the system is awake the resume callback ensures
that the charger is running off of the 19.2 MhZ clock
which does not allow the charger to lock up. Therefore
if the battery alarm wakes up the device before hitting
UVLO the charger hardware will not be in hardware clock
switching mode.

This driver supports the Qualcomm PNP clkdiv peripheral. It
allowed for configuring divide factors for various clock outputs
on the PMIC. The source clock is CXO.
The driver allows for configuration of the clkdiv device through
Device Tree. Some optional parameters may be specified instead at
runtime with the qpnp_clkdiv_config() API.

When v4l2 streamon() is called the framework moves to streamon state,
after queueing the buffer. A state check is performed during dqbuf().
Sometimes when dqbuf() is called streamon() function has not completed
setting the state transisiton flag. This results in failure to dqbuf() as
the framework has not moved to streamon. This patch adds a mutex
around state transitions and dqbuf() calls.

It was observed that while charging the reported soc sometimes reaches
100% before end of charging happens. At other times it does not reach
100% at end of charge and a abrupt jump to 100% soc happens.
Fix this by linearly increasing soc based on battery charge current
after constant voltage phase is reached. Constant voltage phase is
reached when battery voltage reaches the max value.
Also once constant voltage phase is reached and the voltage or charge
current decreases keep reporting the earlier soc. This could be because
of a transient system load.

The "adjust_soc" algorithm where we change the open circuit voltage
(ocv) in steps so that the state of charge (soc) starts approaching
the estimated soc, causes nonlinearity in the soc curves if an incorrect
resistance value is fed to the algorithm.
As battery ages and temperature changes, it is hard to estimate the
exact battery resistance.
So to fix the nonlinearity, limit the amount by which the ocv is
changed. Make it proportional to the current, i.e. change ocv by
small amounts in light load and let it change by proportionally
large amounts in heavy load situations.
Also, make the point where the soc is adjusted configurable via platform
data instead of forcing it to 25%.
