Add a vbb-supply phandle to the cpus node and also add an additional
triplet of voltages for each OPP in the operating-points-v2 table to
make use of the multi regulator support in the OPP core and provide the
vbb regulator for use by the ti-opp-supply driver.

Sounds like these depend on the ti-opp-supply being available first?

Yes that would be best, but the ti-opp-supply patches are already in linux-next.

OK applying into omap-for-v4.16/dt then thanks.
