Thanks for the feedback!

We understand the concern about potential regressions on older SOM
revisions. However, since the wireless module is soldered on the SOM
and not configurable, we are aligning the upstream device tree with
the hardware revision that is currently in production.

This change also aligns the i.MX8MM VAR-SOM with other VAR-SOM
platforms already present in mainline (e.g. i.MX8MP, i.MX93), which
use the IW61x wireless module as well. The intention is to keep the
VAR-SOM family consistent in mainline with the hardware that is
actively produced.

If there is a strong requirement to preserve an explicit description
of the older Broadcom-based revision in mainline, we can evaluate
adding a separate description.

Best regards,
Stefano
