This patch adds support for the tps65090 charger driver. This driver is
responsible for controlling the charger aspect of the tps65090 mfd.
Currently, this mainly consists of turning on and off the charger, but
some features of the charger can be supported through this driver
including:
- Enable Auto Recharge based on Battery voltage
- Fast Charge Safety Timer
- Maximum battery discharge current
- Maximum battery adapter current
- Enable External Charge
- Disable charging termination based on low charger current (supported)
Once the driver is accepted, later patches can add support for the
features above which are not yet supported.

Timers used for charging safety and maintenance must work even when
CPU power has collapsed. By using hrtimers with the realtime clock
the system is able to trigger an alarm that wakes-up the CPU and makes
it possible to handle events.
Allow a little slack time of 5 minutes for the hrtimers to allow CPU
to be woken-up in a more optimal power saving way. A 5 minute delay
to time-out timers relative to hours does not impact on safety.
