[08/20] ARM: dts: sun4i: Change LRADC node names to avoid warnings

Message ID 14fb41e6a5648f99643629b1dc9df9ef04c01fbd.1507198895.git-series.maxime.ripard@free-electrons.com

Commit Message

One of the usage of the LRADC is to implement buttons. The bindings define
that we should have one subnode per button, with their associated voltage
as a property.

However, there was no reg property but we still used the voltage associated
to the button as the unit-address, which eventually generated warnings in
DTC.

Rename the node names to avoid those warnings.

I think 800mV-button would be better, i.e. have the "generic"
part of the name as a suffix.

It would go against most of the convention that we have everywhere
else for framebuffers, pin muxings, or even regular node names that
start with the class, and then have the most specific part.
