From: Cosmin Tanislav Date: Fri, 18 Nov 2022 15:08:09 +0000 (+0200) Subject: watchdog: dw_wdt: stop on reboot X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7bfd2747d3ec2c400857084527448c172a720d2a;p=linux.git watchdog: dw_wdt: stop on reboot HW running watchdogs are just watchdogs that are enabled before the Linux driver is probed, usually by the bootloader (eg. U-Boot). When the system is shutting down, the mechanism for keeping a HW running watchdog pinged is also stopped, but the watchdog itself is not stopped, causing a reset, and preventing the system from being shut down. Opt into stopping watchdogs on reboot.
