How about this wording:

Commit d7a5502b0bb8b ("net: broadcom: convert to
devm_platform_ioremap_resource_byname()")
inadvertently made idm_base and nicpm_base mandatory. These are
optional properties.
probe will fail when they're not defined. The commit is partially
reverted so that they are
obtained by platform_get_resource_byname() as before. amac_base can
still be obtained
by devm_platform_ioremap_resource_byname().
