    Subject[PATCH 5.4 157/222] net: dsa: bcm_sf2: Configure IMP port for 2Gb/sec
    Date
    From: Florian Fainelli <f.fainelli@gmail.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")
