The userspace should be updated periodically to update it with the

Create a delayed_work and schedule it every update_time milliseconds
to notify the userspace that power supply changed. The userspace
is then supposed to read the power supply properties and know about
the charging progress.

The reset interrupt in the pmic indicates the pmic will shutdown
the msm in few seconds - it does so by lowering the reset_n line
to the msm.
When this interrupt is triggered it is required that no more ssbi
transactions are initiated and the msm should cleanup and prepare
for the impending shutdown. There is no need to lower ps_hold in
this case as the pmic will shutdown the msm regardless.
Also since we don't want any ssbi transactions, force shutdown
nonboot cpus. This will prevent ssbi transactions to the pmic for
lower/raising nonboot cpu's voltages as they enter/exit idle states.

microphones and digital microphones. As it is now, micbias voltage level
of WCD9310 is left to default value. Micbias and cfilter mapping is managed
