From 9d7c09231e81a3a21a3dee29b97ca034c94a96b6 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Thu, 11 Apr 2019 21:14:37 +0200 Subject: [PATCH] watchdog: pnx4008: readout watchdog state Readout the enabled state so it is possible to get the pre-userspace handler working. Also, avoid disabling the watchdog to ensure it continues working and triggers if there is an issue later in the boot or if userspace fails to start.
