From f606c9a8959728f7df539e182fb799d3ccc92cc6 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Mon, 15 Nov 2021 23:45:43 +0100 Subject: watchdog: add sl28cpld watchdog driver The watchdog timer is part of the sl28cpld management controller. The watchdog timer usually supervises the bootloader boot-up and if it bites the failsafe bootloader will be activated. Apart from that it supports the usual board level reset and one SMARC speciality: driving the WDT_TIMEOUT# signal.
