This is a note to let you know that I've just added the patch titled ARM: dts: at91: sam9g20ek: enable udc vbus gpio pinctrl to the 5.4-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-sam9g20ek-enable-udc-vbus-gpio-pinctrl.patch and it can be found in the queue-5.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 7e8b53845353cba3ba5d9c7f518c1465473be8ee Author: Michael Grzeschik <m.grzeschik@xxxxxxxxxxxxxx> Date: Mon Nov 14 19:59:23 2022 +0100 ARM: dts: at91: sam9g20ek: enable udc vbus gpio pinctrl [ Upstream commit 40a2226e8bfacb79dd154dea68febeead9d847e9 ] We set the PIOC to GPIO mode. This way the pin becomes an input signal will be usable by the controller. Without this change the udc on the 9g20ek does not work.
