Subject: net: broadcom: Select BROADCOM_PHY for BCMGENET
Git-commit: 99addbe31f5524494f4d7077bcb3f6fa64c5d160
Patch-mainline: v5.7-rc6
References: git-fixes

The GENET controller on the Raspberry Pi 4 (2711) is typically
interfaced with an external Broadcom PHY via a RGMII electrical
interface. To make sure that delays are properly configured at the PHY
side, ensure that we the dedicated Broadcom PHY driver
(CONFIG_BROADCOM_PHY) is enabled for this to happen.
