[PATCH RFC v4 05/13] regulator: introduce properties for monitoring workarounds

[Benjamin Bara]

From: Benjamin Bara <benjamin.bara@xxxxxxxxxxx>

These are useful when the state of the regulator might change during
runtime, but the monitors state (in hardware) are not implicitly changed
with the change of the regulator state or mode (in hardware). Also, when
the monitors should be disabled while ramping after a set_value() or
when the regulator can enter a certain mode in which the monitoring does
not result in a valid state.
