From f254a46809a09f14f82ab6fcf5d28d2f60e0547b Mon Sep 17 00:00:00 2001 From: Marcel Ziswiler Date: Sat, 9 Oct 2021 22:41:13 +0200 Subject: [PATCH] verdin-imx8mm: fix watchdog pinctrl issue Finally, found the root cause of the issue already once mentioned back here [2] which caused the following error message during boot: imx_wdt watchdog@30280000: pinctrl_select_state_full: uclass_get_device_by_phandle_id: err=-19 Turns out while the watchdog node itself was already u-boot,dm-spl its pinctrl node was not which caused it to be unavailable at that early stage. Note that any and all other boards I checked also seem to be missing this. However, I can't judge whether or not they might indeed need a similar fix or not.
