This is a note to let you know that I've just added the patch titled ARM: dts: uniphier: Change phy-mode to RGMII-ID to enable delay pins for RTL8211E to the 5.10-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-uniphier-change-phy-mode-to-rgmii-id-to-enab.patch and it can be found in the queue-5.10 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 43335ab14c401d28ad7677db8182ace8e5e235f3 Author: Kunihiko Hayashi <hayashi.kunihiko@xxxxxxxxxxxxx> Date: Fri Apr 23 02:31:48 2021 +0900 ARM: dts: uniphier: Change phy-mode to RGMII-ID to enable delay pins for RTL8211E [ Upstream commit 9ba585cc5b56ea14a453ba6be9bdb984ed33471a ] UniPhier PXs2 boards have RTL8211E ethernet phy, and the phy have the RX/TX delays of RGMII interface using pull-ups on the RXDLY and TXDLY pins. After the commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx delay config"), the delays are working correctly, however, "rgmii" means no delay and the phy doesn't work. So need to set the phy-mode to "rgmii-id" to show that RX/TX delays are enabled.
