After enabling CONFIG_REGULATOR_DEBUG=y we observe below debug logs.
Changes help link VDDCPU pwm regulator to 12V regulator supply
instead of dummy regulator.
[ 11.602281] pwm-regulator regulator-vddcpu: Looking up pwm-supply property
in node /regulator-vddcpu failed
[ 11.602344] VDDCPU: supplied by regulator-dummy
[ 11.602365] regulator-dummy: could not add device link regulator.11: -ENOENT
[ 11.602548] VDDCPU: 721 <--> 1022 mV at 1022 mV, enabled
