That's probably slightly better. In general, the point is that the
'compatible' property could potentially contain multiple values, e.g. when
there is introduced a common more generic compatible value for a set
of sensors. However your documentation now says that only one specific value
is allowed. I'm adding Mark at Cc, perhaps he can explain it better.

Please don't consider it as an objection from my side, since we now have
mixture of "must be", "should be", "should contain", etc. across the
DT binding documentation files.
