From 2d63908bdbfbce0d98195b22236ad5105dc6eba2 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Thu, 12 Mar 2020 11:58:07 +0200 Subject: watchdog: Add K3 RTI watchdog support Texas Instruments K3 SoCs contain an RTI (Real Time Interrupt) module which can be used as a watchdog. This IP provides a support for windowed watchdog mode, in which the watchdog must be petted within a certain time window. If it is petted either too soon, or too late, a watchdog error will be triggered.
