I don't think this is correct. lazor-rev9 has the Parade bridge chip,
not the TI bridge chip. It can't be lumped together with the earlier
revisions. What you want to do is leave the "rev3 - 8" alone, then add
a new entry just for "-rev9". Your brand new revision 10 doesn't need
its own entry in this list because it's the "newest rev".

nit: please put a space before "(newest rev)"

You're missing the second item: "const: qcom,sc7180"
