[PATCH v2 1/2] regulator: dt-bindings: fixed-regulator: Add under-voltage interrupt support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add under-voltage interrupt support. This can be used with simple
regulators having no other way to communicate an under-voltage event
except as by toggling some GPIO line.
