This is a note to let you know that I've just added the patch titled ARM: dts: at91: tse850: the emac<->phy interface is rmii to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: arm-dts-at91-tse850-the-emac-phy-interface-is-rmii.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 39ff43781929d6c51d5276dded095ac0e326858a Author: Peter Rosin <peda@xxxxxxxxxx> Date: Mon Sep 20 22:37:38 2021 +0200 ARM: dts: at91: tse850: the emac<->phy interface is rmii [ Upstream commit dcdbc335a91a26e022a803e1a6b837266989c032 ] This went unnoticed until commit 7897b071ac3b ("net: macb: convert to phylink") which tickled the problem. The sama5d3 emac has never been capable of rgmii, and it all just happened to work before that commit.
