Yes it is.

I think I’ve followed the feedback done here [1]
I’ve declared `minItems: 2` globally and override it to 4 if
mediatek,mt8365-pwrap is used. Isn’t it the right way to implement it
?

There are no warnings when compile testing. I will fix the unit
address anyway, sorry.

Put the pmic in the example have 2 constraints:
- The original pmic "mediatek,mt6397" isn’t supported by a yaml
schema, so I’ve a dt_binding_check fail: `failed to match any schema
with compatible: ['mediatek,mt6397']`
- If I put another pmic that supports a yaml schema, I need to put all
required properties for the pmic, which I thought was unnecessary
since it’s already done in its own schema and can change for another
pmic, so less consistent.
Then yes, IMHO, PMIC should be skipped in the example.
