Subject: bgmac-enet driver broken in 5.7

Hi,

Commit d7a5502b0bb8b (net: broadcom: convert to
devm_platform_ioremap_resource_byname()) broke the bgmac-enet driver.
probe fails with -22. idm_base and nicpm_base were optional. Now they
are mandatory. Our upstream dtb doesn't have them defined. I'm not
clear on why this change was made. Can it be reverted?

Thanks,
Jon
