Subject: [PATCHv2 2/3] ARM: dts: meson8b: mxq: Fix the pwm regulator supply properties
Date: Mon, 5 Jul 2021 11:23:54 +0000 [thread overview]
Message-ID: <20210705112358.3554-3-linux.amoon@gmail.com> (raw)
In-Reply-To: <20210705112358.3554-1-linux.amoon@gmail.com>
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")
