This is a note to let you know that I've just added the patch titled dt-bindings: gpio: altera: correct interrupt-cells 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: dt-bindings-gpio-altera-correct-interrupt-cells.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. >From 3a21c3ac93aff7b4522b152399df8f6a041df56d Mon Sep 17 00:00:00 2001 From: Dinh Nguyen <dinguyen@xxxxxxxxxx> Date: Wed, 11 May 2022 12:54:46 -0500 Subject: dt-bindings: gpio: altera: correct interrupt-cells From: Dinh Nguyen <dinguyen@xxxxxxxxxx> commit 3a21c3ac93aff7b4522b152399df8f6a041df56d upstream. update documentation to correctly state the interrupt-cells to be 2.
