From 7c6719a1aaca51ffd7cdf3905e70aa8313f6ef26 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 19 Jul 2020 12:00:40 +0100 Subject: arm64: dts: clearfog-gt-8k: fix switch link configuration The commit below caused a regression for clearfog-gt-8k, where the link between the switch and the host does not come up. Investigation revealed two issues: - MV88E6xxx DSA no longer allows an in-band link to come up as the link is programmed to be forced down. Commit "net: dsa: mv88e6xxx: fix in-band AN link establishment" addresses this. - The dts configured dissimilar link modes at each end of the host to switch link; the host was configured using a fixed link (so has no in-band status) and the switch was configured to expect in-band status. With both issues fixed, the regression is resolved.
