[PATCH 1/3] dt-bindings: rtc: add trickle-voltage-mV

From: Alexandre Belloni
Date: Mon Sep 21 2020 - 13:29:42 EST


Some RTCs have a trickle charge that is able to output different voltages
depending on the type of the connected auxiliary power (battery, supercap,
...). Add a property allowing to specify the necessary voltage.
