| Subject: watchdog: kempld-wdt: Use the correct value when configuring the prescaler with the watchdog |
| |
| From: gundberg <per.gundberg@icomera.com> |
| |
| commit a9e0436b303e94ba57d3bd4b1fcbeaa744b7ebeb upstream. |
| |
| Use the prescaler index, rather than its value, to configure the watchdog. |
| This will prevent a mismatch with the prescaler used to calculate the cycles. |
