Subject: [PATCHv2 1/3] arm64: dts: meson-g12a: Fix the pwm regulator supply properties
Date: Sun, 19 Sep 2021 20:29:09 +0000 [thread overview]
Message-ID: <20210919202918.3556-2-linux.amoon@gmail.com> (raw)
In-Reply-To: <20210919202918.3556-1-linux.amoon@gmail.com>
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")
