Subject: [PATCH 4.14 67/89] net: dsa: bcm_sf2: Configure IMP port for 2Gb/sec
From: Florian Fainelli <f.fainelli@...il.com>
[ Upstream commit 8f1880cbe8d0d49ebb7e9ae409b3b96676e5aa97 ]
With the implementation of the system reset controller we lost a setting
that is currently applied by the bootloader and which configures the IMP
port for 2Gb/sec, the default is 1Gb/sec. This is needed given the
number of ports and applications we expect to run so bring back that
setting.
Fixes: 01b0ac07589e ("net: dsa: bcm_sf2: Add support for optional reset controller line")
