From: Colin Foster Date: Fri, 17 Mar 2023 18:54:14 +0000 (-0700) Subject: net: dsa: felix: allow serdes configuration for dsa ports X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6865ecee385bc91d47e6a1801fdf70732e33a6fd;p=linux.git net: dsa: felix: allow serdes configuration for dsa ports Ports for Ocelot devices (VSC7511, VSC7512, VSC7513 and VSC7514) support external phys. When external phys are used, additional configuration on each port is required to enable QSGMII mode and set external phy modes. Add a configurable hook into these routines, so the external ports can be used. Signed-off-by: Colin Foster Signed-off-by: David S.
