From d69de993237b8f106b408313d01b67a6e5d13f1f Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 24 Mar 2023 13:38:33 -0700 Subject: [PATCH] media: rc: gpio-ir-recv: Fix support for wake-up [ Upstream commit 9c592f8ab114875fdb3b2040f01818e53de44991 ] The driver was intended from the start to be a wake-up source for the system, however due to the absence of a suitable call to device_set_wakeup_capable(), the device_may_wakeup() call used to decide whether to enable the GPIO interrupt as a wake-up source would never happen. Lookup the DT standard "wakeup-source" property and call device_init_wakeup() to ensure the device is flagged as being wakeup capable.
