+Subject: [PATCH] arm64: dts: fsl: ls1028a: Specify that the Felix port 4 runs
+ at 2.5Gbps
+
+This is just an informative change, because all Felix MACs inside the
+LS1028A are hardwired in gigabit mode anyway.
+
+Only PHYLINK is able to understand fixed-link speeds higher than 1 Gbps.
+With PHYLIB, fixed-link interfaces are emulated as C22 PHYs by the swphy
+driver, and C22 does not specify settings for speeds higher than
+gigabit.
+
+This patch brings no functional change except for the messages printed
+during driver initialization.
