[PATCH v2 06/10] dt-bindings: rtc: Add bindings for Netronix embedded controller RTC
From: Jonathan Neuschäfer <j.neuschaefer@gmx.net>
Date: 2020-09-05 13:53:58
Also in:
linux-arm-kernel, 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.
Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net>

v2:
- Add plaintext binding to the patch description, for reference
For reference, here is the binding in text form:
Netronix embedded controller RTC
Required properties:
- compatible: should be "netronix,ntxec-rtc"
Example:
embedded-controller@43 {
compatible = "netronix,ntxec";
...
rtc {
compatible = "netronix,ntxec-rtc";
};
}
