[PATCHv2 1/3] arm64: dts: meson-g12a: Fix the pwm regulator supply properties

From: Anand Moon <hidden>
Date: 2021-09-19 20:29:43
Also in: linux-amlogic, linux-devicetree, lkml
Subsystem: arm/amlogic meson soc support, the rest · Maintainers: Neil Armstrong, Kevin Hilman, Linus Torvalds

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")
