-Generic device tree bindings for Real Time Clock devices
-========================================================
-
-This document describes generic bindings which can be used to describe Real Time
-Clock devices in a device tree.
-
-Required properties
--------------------
-
-- compatible : name of RTC device following generic names recommended practice.
-
-For other required properties e.g. to describe register sets,
-clocks, etc. check the binding documentation of the specific driver.
-
-Optional properties
--------------------
-
-- start-year : if provided, the default hardware range supported by the RTC is
- shifted so the first usable year is the specified one.
-
-The following properties may not be supported by all drivers. However, if a
-driver wants to support one of the below features, it should adapt the bindings
-below.
-- trickle-resistor-ohms : Selected resistor for trickle charger. Should be given
- if trickle charger should be enabled
-- trickle-diode-disable : Do not use internal trickle charger diode Should be
- given if internal trickle charger diode should be
- disabled
-- wakeup-source : Enables wake up of host system on alarm
-- quartz-load-femtofarads : The capacitive load of the quartz(x-tal),
- expressed in femto Farad (fF).
- The default value shall be listed (if optional),
- and likewise all valid values.

The real time clocks have a bunch of generic properties that are needed in a device tree. Add a YAML schemas for those.
