From 6674a90bb141496f56ce840c22f2f2ddccc5d397 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Sat, 20 Feb 2021 13:49:51 +0100 Subject: [PATCH] arm64: dts: ti: k3-am65-mcu: Add RTI watchdog entry Add the DT entry for a watchdog based on RTI1. On SR1.0 silicon, it requires additional firmware on the MCU R5F cores to handle the expiry, e.g. https://github.com/siemens/k3-rti-wdt. As this firmware will also lock the power domain to protect it against premature shutdown, mark it shared.
