Add a bit mask to enable workarounds only if they are needed for a
particular hardware revision.

Currently the SOC in userspace is not being updated with the latest SOC
from the fuel gauge. Add power supply changed events when the delta SOC
interrupt fires, empty SOC interrupt fires, or when the charging status
changes to full.

The fuel gauge can count the number of times the battery has charged
across a particular SOC range. Enable it.

The SOC range is divided into buckets. Whenever the battery is charged
across a bucket we increment the counter for that bucket. These cycle
counters are exposed through the "cycle_counter" property, and buckets
are selected by modifying the "cycle_counter_id" property.

Currently userspace will be notified whenever the Type-C changed
interrupt fires. The charging status reflects whether or not the charger
has a valid input power source. The valid input power source status
follows vbus and not the Type-C changed logic, so in some cases the
charging status may not yet be updated when the userpace is notified
that the USB power supply has changed.
Send a USB power supply changed event when both the Type-C changed
interrupt fires, and the USB plugin interrupt fires.

This DT bindings documentation snapshot is taken as of msm-3.18
'commit b428af643156 ("power: qpnp-fg: configure thermal coefficients based on battery type")'
While at it, change the name used in the documentation from
Qualcomm to Qualcomm Technologies, Inc.

There are some encoding changes to the following configurations
in pmi8998 SRAM. Update them.
For both v1.1 and v2.0,
- No sign bit for charge termination current
For v2.0,
- 6 bit encoding for empty voltage and vbatt_low
While at it, fix the SRAM byte location from byte 2 to byte 3 for
configuring empty voltage threshold in pmi8998v2.0.

healthd expects battery voltage, current, temperature, and technology from
the battery power supply. Add them.

The fuel gauge has several algorithm flags which are useful for
debugging. Add a debugfs file called alg_flags to expose them.
