From 1d9ffbc6b185561c65a5a599562dbb6c5d66e7d1 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 16 Feb 2021 13:39:58 +0100 Subject: [PATCH] soc: renesas: rmobile-sysc: Mark fwnode when PM domain is added Currently, there are two drivers binding to the R-Mobile System Controller (SYSC): - The rmobile-sysc driver registers PM domains from a core_initcall(), and does not use a platform driver, - The optional rmobile-reset driver registers a reset handler, and does use a platform driver. As fw_devlink only considers devices, commit bab2d712eeaf9d60 ("PM: domains: Mark fwnodes when their powerdomain is added/removed") works only for PM Domain drivers where the DT node is a real device node, and not for PM Domain drivers using a hierarchical representation inside a subnode. Hence if fw_devlink is enabled, probing of on-chip devices that are part of the SYSC PM domain is deferred until the optional rmobile-reset driver has been bound. If the rmobile-reset driver is not available, this will never happen, and thus lead to complete system boot failures. Fix this by explicitly marking the fwnode initialized.
