   4 Subject: [PATCH] arm64: dts: fsl: ls1028a: Specify that the Felix port 4 runs
   5  at 2.5Gbps
   6
   7 This is just an informative change, because all Felix MACs inside the
   8 LS1028A are hardwired in gigabit mode anyway.
   9
  10 Only PHYLINK is able to understand fixed-link speeds higher than 1 Gbps.
  11 With PHYLIB, fixed-link interfaces are emulated as C22 PHYs by the swphy
  12 driver, and C22 does not specify settings for speeds higher than
  13 gigabit.
  14
  15 This patch brings no functional change except for the messages printed
  16 during driver initialization.
