[ 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

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
