Hi Anand,

I (as non-native english speaker) suggest rewording this to:
After enabling CONFIG_REGULATOR_DEBUG=y we observe below debug logs.

excellent catch, thanks for sending a patch!

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

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


Best regards,
Martin
