| Subject: watchdog: keembay: Upadate WDT pretimeout for every update in timeout |
| |
| From: Shruthi Sanil <shruthi.sanil@intel.com> |
| |
| [ Upstream commit 0f7bfaf10c0abc979220442bae2af4f1f869c41e ] |
| |
| 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. |
| |
| Fixes: fa0f8d51e90d ("watchdog: Add watchdog driver for Intel Keembay Soc") |
