As Mark said, these all need documentation.

Better if you tab these out, like:
- compatible : Should be "hisilicon,hi655x-pmic-driver"
- reg : Base address of PMIC on hi6220 soc
Etc ...

Small a => f please.

This should be <name>-gpios.
No underscores please.

Use "okay" instead.

White space issues here.
Where is the 'reg' property?

Use #defines (same goes for all below).

White space in a name seems wrong to me.

What is @1?
Is this label used?

Documentation? It doesn't look like a generic propriety either, so
should be have a vendor prefix.

"okay"

What's this? No IDs in DT please.

Whitespace.
'reg'?

Tabbing seems wrong here.

All of these vendor properties need documenting and signing of by Mark
(the Regulator Maintainer).
