Minor nit, s/suspend-opp/suspend_opp
and here is updated patch

Subject: [PATCH V8] OPP: Add binding for 'opp-suspend'
On few platforms, for power efficiency, we want the device to be
configured for a specific OPP while we put the device in suspend state.
Add an optional property in operating-points-v2 bindings for that.
