Subject: [PATCHv1] arm64: amlogic: Fix the pwm regulator supply property in node
Date: Tue, 29 Jun 2021 12:18:47 +0000 [thread overview]
Message-ID: <20210629121848.6527-1-linux.amoon@gmail.com> (raw)
On enable CONFIG_REGULATOR_DEBUG=y we observer below debug logs.
Changes help link VDDCPU_A and VDDCPU_B pwm regulator to 12V regulator
supply instead of dummy regulator.
[ 4.147196] VDDCPU_A: will resolve supply early: pwm
[ 4.147216] pwm-regulator regulator-vddcpu-a: Looking up pwm-supply from device tree
[ 4.147227] pwm-regulator regulator-vddcpu-a: Looking up pwm-supply property in node /regulator-vddcpu-a failed
[ 4.147258] VDDCPU_A: supplied by regulator-dummy
[ 4.147288] regulator-dummy: could not add device link regulator.12: -ENOENT
[ 4.147353] VDDCPU_A: 721 <--> 1022 mV at 871 mV, enabled
[ 4.152014] VDDCPU_B: will resolve supply early: pwm
[ 4.152035] pwm-regulator regulator-vddcpu-b: Looking up pwm-supply from device tree
[ 4.152047] pwm-regulator regulator-vddcpu-b: Looking up pwm-supply property in node /regulator-vddcpu-b failed
[ 4.152079] VDDCPU_B: supplied by regulator-dummy
[ 4.152108] regulator-dummy: could not add device link regulator.13: -ENOENT
