This is already done in the SoM dtsi, same applies to the other comment
you have on this pinmux topic.
To rephrase what's hopefully is already written in the commit
message/series description, or at least it was in my intention.
The system is modular, with multiple SoM variant and multiple carrier
boards. Standard interfaces are defined at the family level, e.g.
already in the SoM, in the carrier board DT file peripherals are just
enabled, the pinmux is already defined in the common som.dtsi [1][2][3]
files and the carrier board just use those unless there is some kind of
non-standard deviation.
This prevents duplication and simplify writing device tree file for board
that use standard Verdin family interfaces. This should be visible
looking at this series in which 3 different boards (Dev, Yavia and
Dahlia) are added.
All of that is clearly defined in our datasheets and publicly available
documentation.
