The RTC generic bindings has a bunch of devices that have a pretty simple
binding, with just compatible, reg and optional interrupts properties.
This is exactly what the trivial devices YAML schema has been created for,
so let's move those devices there.

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

-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 older Allwinner SoCs have an embedded RTC supported in Linux, with a
matching Device Tree binding.
Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

-The RTC provides the following clocks at the given indices:

The R40 has a pretty different RTC compared to the other SoCs we've
encountered so far, the most important difference being that it now has
only a single interrupt, compared to the previous SoCs having two.
Let's add a compatible for that.

The RTC node doesn't match what is described in the binding for historical
reasons. Let's add the proper description.

The A31 datasheet mandates oscillators accuracy to be within 50ppm. Let's
add that accuracy to their device tree nodes.

For some reason, while the v3s has a dedicated compatible in the RTC
binding, the one actually used was the A31's. However, it turns out that
the controller is pretty different (which justified the compatible).
Let's use the proper compatible, and use the proper binding description as
well.

Unlike what's being reported in the device tree so far, the RTC in the R40
is quite different from the H3. Indeed it doesn't have the internal
oscillator output, and it has only a single interrupt. Let's add a
compatible for it.

This is not true, they all also support the star-year property, this is

Ok, I misunderstood the binding then.
Should we create a separate file for the trivial RTC, on the model of
the trivial-devices but supporting all the RTC properties?

I would say that this is the way forward. Note that all the RTCs support
start-year but you will have to check for the other properties.

Without understanding the full detains of JSON schema, the new description

You should probably mention the R40 compatible was dropped in favor of
the new one in the next patch. Or was that an error?

The way this will work is that it's a two layers thing. Patch 2
creates a generic RTC binding schema that will match on two things:
- Schemas including it directly,
- any devicetree node following the node name pattern.
The point of that schema is to validate that every node (or binding),
if it has those properties, the schemas will make sure that it's the
proper type, (and if we would have any) ranges, etc.
Then, it's up for the driver schemas to do a more on-point validation,
with whatever constraints they have. They can choose to restrict the
set of properties, or not to, it's really up to the device schema.
