[ Upstream commit 0b26fa8a02c2834f1fa8a206a285b9f84c4ad764 ]
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
