Subject: [PATCH v8 3/5] arm64: dts: ti: k3-am65-mcu: Add RTI watchdog entry
Date: Sat, 18 Sep 2021 08:17:54 +0200 [thread overview]
Message-ID: <789827a988a4ca6b418edb55e205918812564fd9.1631945876.git.jan.kiszka@siemens.com> (raw)
In-Reply-To: <cover.1631945876.git.jan.kiszka@siemens.com>
From: Jan Kiszka <jan.kiszka@siemens.com>
Add the DT entry for a watchdog based on RTI1. 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.
Aligns us to the kernel's DT in this regard.
