| Subject: arm64: dts: meson-g12a: Fix the pwm regulator supply properties |
| |
| From: Anand Moon <linux.amoon@gmail.com> |
| |
| [ Upstream commit 085675117ecf5e02c4220698fd549024ec64ad2c ] |
| |
| 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") |
