[ Upstream commit 62183863f708c2464769e0d477c8ce9f3d326feb ]
After enabling CONFIG_REGULATOR_DEBUG=y we observer below debug logs. Changes help link VDDCP_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
