Subject[PATCHv2 3/3] ARM: dts: meson8b: ec100: Fix the pwm regulator supply properties
Date
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.

[ 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: 087a1d8b4e4c ("ARM: dts: meson8b: ec100: add the VDDEE regulator")
Fixes: 3e7db1c1b7a3 ("ARM: dts: meson8b: ec100: improve the description of the regulators")
