Subject: [PATCH] arm64: dts: meson-g12a: Fix the pwm regulator supply properties
Git-commit: 085675117ecf5e02c4220698fd549024ec64ad2c
Patch-mainline: v5.16-rc1
References: stable-5.14.19
[ 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
