[PATCH v5 1/2] Documentation: dt-bindings: trickle charger dt binding document for ds1339
From: Matti Vaittinen <hidden>
Date: 2014-09-09 13:29:10
Also in:
lkml
Subsystem:
i2c subsystem host drivers, open firmware and flattened device tree bindings, real time clock (rtc) subsystem, the rest · Maintainers:
Andi Shyti, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Alexandre Belloni, Linus Torvalds
Some DS13XX devices have "trickle chargers". Introduce a device tree binding
for the resistor and diode configuration for enabling trickle charger.
