It would be more intuitive to the reader, when the enabled node would
use an explicit
status = "enabled";

What does ""okay" mean? This is not documented anywhere. Is this
supposed to mean "enabled"? Then please write "enabled" - for certain
configurations it is definitely OK to disable the device.

There's an old story about the person who wished his computer were as
easy to use as his telephone. That wish has come true, since I no
longer know how to use my telephone.
