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.

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%.

When a strong battery is removed, it was seen that the battery voltage
lines on the phone take about five to six seconds to go below 2.1volts
where the pmic resets all the battery backed registers.
If a new battery is plugged in within this time the driver will force
the shutdown soc on this battery which is incorrect.
Compare the shutdown soc with the calculated soc and if they are
different than a configurable limit, simply discard the shutdown soc
and use the calculated soc.

The dynamic UUC algorithm changes the UUC as load, state of charge and
temperature changes. This uncontrolled behaviour causes unacceptable
jumps in state of charge numbers.
Replace the dynamic UUC algorithm with a simple average current based
UUC. The average current is calculated by remembering the load for last
few (16) samples. Also to maintain a reasonable UUC while charging, a
load of 300mA is assumed.
Note that the first time UUC is calculated we don't have load samples
and in that case the instantaneous current is used.
Since we now don't change the UUC with respect to max possible load
(itest), the usage of this value is removed. Also instead of failure
voltage we introduce cutoff voltage which represents the loaded voltage
by which the battery should be reported 0%.

If the battery fet is open, the current sourced or sinked from the
battery is very low. There is a high chance that an open circuit
voltage(OCV) happens. Putting the BMS in override mode resets the timer
whose expiry causes an OCV.
Avoid putting the BMS in override mode if battery fet is open.

There is a corner case in the tty driver where the value of
tty->receive_room is not being updated before writing data to
the line discipline. When this happens, data is lost because
of failure to re-submit any remaining data to the ldisc.
This fix is dependent on a new tty flag that is set only when
the tty driver is used for efs sync betweem the mdm modem and
the applications processor.
