Subject: [PATCH] ARM: dts: sun7i: lamobo-r1: Fix CPU port RGMII settings
Date: Sat, 18 Mar 2017 21:53:20 -0700 [thread overview]
Message-ID: <20170319045321.6454-1-f.fainelli@gmail.com> (raw)
The CPU port of the BCM53125 is configured with RGMII (no delays) but
this should actually be RGMII with transmit delay (rgmii-txid) because
STMMAC takes care of inserting the transmitter delay. This fixes
occasional packet loss encountered.
Fixes: d7b9eaff5f0c ("ARM: dts: sun7i: Add BCM53125 switch nodes to the lamobo-r1 board")
Reported-by: Hartmut Knaack <knaack.h-Mmb7MZpHnFY@public.gmane.org>
Signed-off-by: Florian Fainelli <f.fainelli-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
