Subject: [PATCH net v2] net: broadcom: Select BROADCOM_PHY for BCMGENET
Date: Wed, 13 May 2020 08:51:51 -0700 [thread overview]
Message-ID: <20200513155158.26110-1-f.fainelli@gmail.com> (raw)
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.
Fixes: 402482a6a78e ("net: bcmgenet: Clear ID_MODE_DIS in EXT_RGMII_OOB_CTRL when not needed")
