Subject: [PATCH] net: dsa: mv88e6xxx: support RGMII cmode
Date: Tue, 16 Aug 2022 13:45:34 +0200 [thread overview]
Message-ID: <20220816114534.10407-1-marcus.carlberg@axis.com> (raw)
Since the probe defaults all interfaces to the highest speed possible
(10GBASE-X in mv88e6393x) before the phy mode configuration from the
devicetree is considered it is currently impossible to use port 0 in
RGMII mode.
This change will allow RGMII modes to be configurable for port 0
enabling port 0 to be configured as RGMII as well as serial depending
on configuration.
