[PATCH 00/11] power: supply: pmi8998 charger improvements and smb5 support

[Casey Connolly <casey.connolly@linaro.org>]

This series contains fixes and cleanups for the pmi8998 charger driver,
as well as introducing support for the newer smb5 charger found in the
pm8150b and other newer Qualcomm PMICs..

A bug is fixed where wakeirq enable/disable refcounting wasn't respected
when the driver was unloaded and reloaded.

Support is added for disabling charging entirely by writing a 0 to the
"status" register (as described in the psy documentation). This allows
for userspace programs to manage charging, e.g. to stop at 80% capacity.

The AICL re-run interval is programmed to a consistent value (3
seconds).

The battery property charge-term-current-microamp is now respected, this
is used to program the constant charge current limit during the fast
charging phase. This also makes it safer to increase the max current
limit this driver originally imposed from 1A to ~2A. According to the
PMIC docs this is easy to handle without a secondary charger chip (which
most but not all phones have).

Further increasing the charge current limit would require tighter
integration with thermal zones and a mechanism to limit the current
when the device gets too warm (e.g. by modelling the power supply as
a cooling device). This infrastructure is currently missing from the
kernel.
