The original Documentation was wrong all along. Fix it while we are converting it. The example was wrong as kpss-acc-v2 should only expose the regs but we don't have any driver that expose additional clocks. The kpss-acc driver is only specific to v1. For this exact reason, limit all the additional bindings (clocks, clock-names, clock-output-names and #clock-cells) to v1 and also flag that these bindings should NOT be used for v2.
