Commit Message

Neil Armstrong Oct. 17, 2022, 10:23 a.m. UTC
  Convert the non-SMD RPM node bindings to dt-schema, the old txt bindings
are now removed since all bindings were converted.

Need to define how many entries.

Can be simplified to this:

'-?regulators$'

However, as there is no constraint as to what comes before the r or -, 
the '-?' doesn't do anything. Either drop it or try to define the 
preceeding part. Perhaps '^([a-z]+-)?regulators$' is what you wanted if 
just 'regulators' is one case?

-Qualcomm Resource Power Manager (RPM)
