Subject: [PATCH 03/10] watchdog: keembay: Update pretimeout to zero in the TH ISR
Date: Wed, 12 May 2021 14:17:17 +0530	[thread overview]
Message-ID: <20210512084724.14634-4-shruthi.sanil@intel.com> (raw)
In-Reply-To: <20210512084724.14634-1-shruthi.sanil@intel.com>

From: Shruthi Sanil <shruthi.sanil@intel.com>

The pretimeout has to be updated to zero during the ISR of the
ThresHold interrupt. Else the TH interrupt would be triggerred for
every tick until the timeout.

Fixes: fa0f8d51e90d ("watchdog: Add watchdog driver for Intel Keembay Soc")
