The list is in the commit description of "[PATCH 19/25] serial: sh-sci: Add
support for optional external (H)SCK input": sh7723, sh7724, and r8a7740.

Note that the list is probably incomplete, so I don't know if it's that useful
to have it in the binding docs. Especially as I haven't verified yet that it
actually works ;-)
