Subject: [PATCH v2 06/10] dt-bindings: rtc: Add bindings for Netronix embedded controller RTC
Date:   Sat,  5 Sep 2020 15:32:26 +0200
Message-Id: <20200905133230.1014581-7-j.neuschaefer@gmx.net>

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.

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 =3D "netronix,ntxec";
  		...

  		rtc {
  			compatible =3D "netronix,ntxec-rtc";
  		};
  	}
