This is a note to let you know that I've just added the patch titled arm64: dts: renesas: beacon: Fix Ethernet PHY mode 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: arm64-dts-renesas-beacon-fix-ethernet-phy-mode.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 3603598678320204bba9cb8c156bbe79c9015c54 Author: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> Date: Fri Sep 24 08:50:23 2021 +0200 arm64: dts: renesas: beacon: Fix Ethernet PHY mode [ Upstream commit 59a8bda062f8646d99ff8c4956adf37dee1cb75e ] While networking works fine in RGMII mode when using the Linux generic PHY driver, it fails when using the Atheros PHY driver. Fix this by correcting the Ethernet PHY mode to RGMII-RXID, which works fine with both drivers.
