Subject: [PATCH v2 2/9] watchdog: keembay: Upadate WDT pretimeout for every update in timeout
Date: Mon, 17 May 2021 23:19:46 +0530	[thread overview]
Message-ID: <20210517174953.19404-3-shruthi.sanil@intel.com> (raw)
In-Reply-To: <20210517174953.19404-1-shruthi.sanil@intel.com>

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

The pre-timeout value to be programmed to the register has to be
calculated and updated for every change in the timeout value.
Else the threshold time wouldn't be calculated to its
corresponding timeout.
