But if we look at the downstream dts (see [1]), we clearly have holes
on gpio 2, 5 and 7 on PMM8155AU_2 whereas if we see [2], we can see
PMM8155AU_1 has holes on gpio 2, 5, 7 and 8.

As I understand, the schematics mention some optional configurations
as well which might not be available depending on the default board
configuration.
