Er, I must note that the colon style here is not consistent with the rest
of the properties, i.e. there's space before the colon here, while in other
cases there's none.

Descriptions should consistently start with a lower case, I think...

Don't think that's a good value, unless this is only a placeholder.

I'd rather label ut phy2...

This is the default "compatible", i.e. there's no need to specify it, IIRC.
