From 7cdee28c4eeda8242c9fdbb02e315dbf35064afe Mon Sep 17 00:00:00 2001 From: Roelof Berg Date: Wed, 3 Jun 2020 23:54:14 +0200 Subject: lan743x: Use correct MAC_CR configuration for 1 GBit speed Corrected the MAC_CR configuration bits for 1 GBit operation. The data sheet allows MAC_CR(2:1) to be 10 and also 11 for 1 GBit/s speed, but only 10 works correctly. Devices tested: Microchip Lan7431, fixed-phy mode Microchip Lan7430, normal phy mode Fixes: 6f197fb63850 ("lan743x: Added fixed link and RGMII support") Signed-off-by: Roelof Berg Reviewed-by: Andrew Lunn Signed-off-by: David S.
