Subject: [PATCH 3/4] arm64: dts: apm: Add "reg" to "syscon-reboot" and "syscon-poweroff"
Date: Tue, 16 Dec 2025 14:27:50 -0600 [thread overview]
Message-ID: <20251216-dt-apm-v1-3-0bf2bf8b982c@kernel.org> (raw)
In-Reply-To: <20251216-dt-apm-v1-0-0bf2bf8b982c@kernel.org>
As the nodes already have a unit-address, add the corresponding "reg"
entry which is preferred over "offset".
Signed-off-by: Rob Herring (Arm) <robh@kernel.org>
