From 81e7c6befa36cecdcbf7244393bd67e8f8c59bf5 Mon Sep 17 00:00:00 2001 From: Saravana Kannan Date: Mon, 11 May 2026 17:57:49 +0200 Subject: of: dynamic: Fix overlayed devices not probing because of fw_devlink When an overlay is applied, if the target device has already probed successfully and bound to a device, then some of the fw_devlink logic that ran when the device was probed needs to be rerun. This allows newly created dangling consumers of the overlayed device tree nodes to be moved to become consumers of the target device. [Herve: Add the call to driver_deferred_probe_trigger()] [Herve: Use fwnode_test_flag() to test fwnode flags value] Fixes: 1a50d9403fb9 ("treewide: Fix probing of devices in DT overlays") Reported-by: Herve Codina Closes: https://lore.kernel.org/lkml/CAMuHMdXEnSD4rRJ-o90x4OprUacN_rJgyo8x6=9F9rZ+-KzjOg@mail.gmail.com/ Closes: https://lore.kernel.org/all/20240221095137.616d2aaa@bootlin.com/ Closes: https://lore.kernel.org/lkml/20240312151835.29ef62a0@bootlin.com/ Signed-off-by: Saravana Kannan Link: https://lore.kernel.org/lkml/20240411235623.1260061-3-saravanak@google.com/ [Herve: Rebase on top of recent kernel] Signed-off-by: Herve Codina Tested-by: Kalle Niemi Tested-by: Geert Uytterhoeven Acked-by: Rob Herring (Arm) Link: https://patch.msgid.link/20260511155755.34428-3-herve.codina@bootlin.com Signed-off-by: Greg Kroah-Hartman --- include/linux/fwnode.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include') diff --git a/include/linux/fwnode.h b/include/linux/fwnode.h index c30a9baafc0d..4e86e6990d28 100644 --- a/include/linux/fwnode.h +++ b/include/linux/fwnode.h @@ -253,6 +253,7 @@ int fwnode_link_add(struct fwnode_handle *con, struct fwnode_handle *sup, u8 flags); void fwnode_links_purge(struct fwnode_handle *fwnode); void fw_devlink_purge_absent_suppliers(struct fwnode_handle *fwnode); +void fw_devlink_refresh_fwnode(struct fwnode_handle *fwnode); bool fw_devlink_is_strict(void); #endif -- cgit v1.2.3
