From 6c253be7ce19bec6dba386fc55f4986de65281d0 Mon Sep 17 00:00:00 2001 From: Michal Simek Date: Mon, 16 Jul 2018 13:34:55 +0200 Subject: [PATCH] watchdog: cdns: Add comment for expire_now function IP itself has no reg/no bit which can be used for this functionality. Add this note to the driver to make sure that none will be asking for that. Current method is to setup 1s timeout and hang() which is done via wdt_expire_now().
