Hi Martin,

Thanks for your review comments.

On enable CONFIG_REGULATOR_DEBUG=y we observer below debug logs.
I (as non-native english speaker) suggest rewording this to:
After enabling CONFIG_REGULATOR_DEBUG=y we observe below debug logs.
Opps: I will fix this in the next version.

Changes help link VCCK and VDDEE pwm regulator to 5V regulator supply
instead of dummy regulator.

excellent catch, thanks for sending a patch!

Thanks
For the subject:
- patches for 32-bit ARM should start with upper-case ARM
- personally I also include the board name so the git history is easier to read

My suggestion for the subject line is:
ARM: dts: meson8b: odroidc1: Fix the pwm regulator supply properties
Ok I will try to incorporate your suggestion in the next version.
Are you also planning to send patches for the following 32-bit SoC boards?
- arch/arm/boot/dts/meson8b-mxq.dts
- arch/arm/boot/dts/meson8b-ec100.dts
Ok I will try to send all updates in the next series.
Best regards,
Martin
