Subject: [PATCH] net: dsa: b53: Drop BCM5301x workaround for a wrong CPU/IMP
port
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
On BCM5301x port 8 requires a fixed link when used.
Years ago when b53 was an OpenWrt downstream driver (with configuration
based on sometimes bugged NVRAM) there was a need for a fixup. In case
of forcing fixed link for (incorrectly specified) port 5 the code had to
actually setup port 8 link.
For upstream b53 driver with setup based on DT there is no need for that
workaround. In DT we have and require correct ports setup.
