[RFC PATCH 07/10] dt-bindings: rtc: Add bindings for Netronix embedded controller RTC
From: Jonathan Neuschäfer <j.neuschaefer@gmx.net>
Date: 2020-06-20 22:43:49
Also in:
linux-pwm, linux-rtc, lkml
Subsystem:
multifunction devices (mfd), netronix embedded controller, open firmware and flattened device tree bindings, real time clock (rtc) subsystem, the rest · Maintainers:
Lee Jones, Jonathan Neuschäfer, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Alexandre Belloni, Linus Torvalds
The Netronix EC implements an RTC with the following functionality: - Calendar-based time keeping with single-second resolution - Automatic power-on with single-minute resolution - Alarm at single-second resolution This binding only supports timekeeping for now.
