The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the driver-core-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From e13f5b7a130f7b6d4d34be27a87393890b5ee2ba Mon Sep 17 00:00:00 2001 From: Saravana Kannan Date: Thu, 21 Jan 2021 14:57:11 -0800 Subject: of: property: Add fw_devlink support for "gpio" and "gpios" binding To provide backward compatibility for boards that use deprecated DT bindings, we need to add fw_devlink support for "gpio" and "gpios". We also need to ignore these properties on nodes with "gpio-hog" property because their gpio[s] are all supplied by the parent node.
