Subject: [PATCHv2 0/3] Fix the pwm regulator supply properties

Changes PWM supply properties help fix internal link of PWM to
main 12V supply as per the shematics.

V1: https://lkml.org/lkml/2021/6/29/288

Thanks

Thanks for fixing all the other boards !

Thanks for working on this!
I haven't runtime tested the patches but I expect that they will work
in the same way that the Meson8/8b/8m2 patches with the same change
did.

Neil, some of these boards are covered by Kernel CI.
I suggest queueing the patches in v5.16/dt64 and then seeing if
there's any feedback from the auto-builders.


Best regards,
Martin
