From 61ee0674bcfd80eaa0173215d38839a48b08b56b Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Tue, 13 Oct 2020 16:41:08 +0200 Subject: dt-bindings: rtc: add trickle-voltage-millivolt 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.
