I wrote this driver to read settings and state from the nxp pf530x
regulator. Please consider it for inclusion, any criticism is welcome.

This revision (v5) adds a proper compatibility designation between devices
in the family, and fixes the devicetree schema to pass the dt_binding_check

Thanks,
Woodrow Douglass

All,

When i submitted this patch, I got a bunch of "unsolicited mail" bounces from gmail. My 
@carnegierobotics.com address is an exchange server with no exposed smtp, so i have to
send patches with `git send-email` via an envelope sender (git@douglass.dev). I suspect 
this is what caused this. I'm sorry for the inconvenience; patch v5 still seems to be 
on the lkml archive.

Thank you,
Woodrow Douglass

Maybe b4 relay will be helpful:
https://b4.docs.kernel.org/en/latest/contributor/send.html

but if you have own SMTP, then could work as well.

Best regards,

I will configure the web relay for future patches, thank you! Should I resubmit patch v5, or is the
fact that it's on the lkml archive good enough? it's at
https://lore.kernel.org/lkml/20250902-pf530x-v5-0-658c403e6a52@carnegierobotics.com/

Thanks,

It came through fine here so I don't need a resend.
