| Subject: ARM: dts: meson8b: mxq: Fix the pwm regulator supply properties |
| |
| From: Anand Moon <linux.amoon@gmail.com> |
| |
| [ Upstream commit 632062e540becbbcb067523ec8bcadb1239d9578 ] |
| |
| After enabling CONFIG_REGULATOR_DEBUG=y we observer below debug logs. |
| Changes help link VCCK and VDDEE pwm regulator to 5V regulator supply |
| instead of dummy regulator. |
| Add missing pwm-supply for regulator-vcck regulator node. |
| |
| [ 7.117140] pwm-regulator regulator-vcck: Looking up pwm-supply from device tree |
| [ 7.117153] pwm-regulator regulator-vcck: Looking up pwm-supply property in node /regulator-vcck failed |
| [ 7.117184] VCCK: supplied by regulator-dummy |
| [ 7.117194] regulator-dummy: could not add device link regulator.8: -ENOENT |
| [ 7.117266] VCCK: 860 <--> 1140 mV at 986 mV, enabled |
| [ 7.118498] VDDEE: will resolve supply early: pwm |
| [ 7.118515] pwm-regulator regulator-vddee: Looking up pwm-supply from device tree |
| [ 7.118526] pwm-regulator regulator-vddee: Looking up pwm-supply property in node /regulator-vddee failed |
| [ 7.118553] VDDEE: supplied by regulator-dummy |
| [ 7.118563] regulator-dummy: could not add device link regulator.9: -ENOENT |
| |
| Fixes: dee51cd0d2e8 ("ARM: dts: meson8b: mxq: add the VDDEE regulator") |
| Fixes: d94f60e3dfa0 ("ARM: dts: meson8b: mxq: improve support for the TRONFY MXQ S805") |
