Kaanapali's DPU is supplied by both CORE and INT2 GDSCs. The
power-domain core only auto-attaches a single domain; with multiple
domains the device is left unattached, so both domains must be attached
explicitly.
The DPU OPP table also needs to continue controlling the MMCX
performance state. Mark CORE as the required OPP domain so its vote is
propagated through the genpd hierarchy to MMCX. INT2 has no OPP of its
own and is attached as a regular runtime-PM supplier.
Platforms with a single power domain remain unaffected and continue to
use the existing automatic attachment.

Where? No tests were at v3 and v4.
