exception to the sort rule
sort regulator-name above all other regulator properties

sort

----
Heiko's sort rules:

compatible
reg
interrupts
[alphabetical]
status [if needed]

With YAML undocumented additional properties and nodes generate
notifications.
We need a change in the documents below for that.
rockchip,dwc3.yaml > usb-drd.yaml > usb.yaml

Is there a standard for the usb-eth nodename?

> + compatible = "realtek,rtl8153";

Since a while Rob has improved has scripts.
There's no escape anymore.
Add a YAML document to this serie for "realtek,rtl8153".

Improve checking for undocumented compatible strings
https://github.com/devicetree-org/dt-schema/commit/93e7ada8d53af099074cb5d53f7caa12835784e0

Why 2 ?

This is a private property.
In a generic dts that's up to the user.
