Subject: [PATCH v2 1/3] dt-bindings: rtc: add trickle-voltage-millivolt
Date: Thu,  8 Oct 2020 00:05:04 +0200	[thread overview]
Message-ID: <20201007220506.360469-1-alexandre.belloni@bootlin.com> (raw)

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.

Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>

Changes in v2:
 - use millivolt suffix instead of mV
