This comment isn't much help. Can we drop it?

Either that, or expand on what it is in each case, e.g.

/*
* Data specific to the match_type.
*
* For ate_match_dt, this is a DT property name to look for.
*/
const void *id;

Elesewhere we just the name desc for strings like this.

Can we s/desc_str/desc/, please?

Thanks,
Mark.
