[ Upstream commit 085675117ecf5e02c4220698fd549024ec64ad2c ]
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
Fixes: e9bc0765cc12 ("arm64: dts: meson-g12a: enable DVFS on G12A boards")
