Subject: [PATCH 3/3] arm: dts: k3: Add RTI watchdogs
Date: Tue, 23 Jun 2020 08:20:26 +0200 [thread overview]
Message-ID: <e2781a696cdecafd6f0e4c69dcaf251a87b30dc3.1592893226.git.jan.kiszka@siemens.com> (raw)
In-Reply-To: <cover.1592893226.git.jan.kiszka@siemens.com>
From: Jan Kiszka <jan.kiszka@siemens.com>
Add DT entries for main domain watchdog0 and 1 instances on the J721e
well as RTI1-based watchdog on the AM65x. RTI0 does not work for this
purpose on the AM65x, so leave it out.
Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
