Subject: [PATCH v5 09/10] arm64: dts: ti: k3-am62a7-sk: Reserve main_rti4 for C7x DSP
Date: Mon, 10 Feb 2025 16:15:29 -0600 [thread overview]
Message-ID: <20250210221530.1234009-10-jm@ti.com> (raw)
In-Reply-To: <20250210221530.1234009-1-jm@ti.com>
From: Hari Nagalla <hnagalla@ti.com>
The main rti4 watchdog timer is used by the C7x DSP, so reserve the
timer in the linux device tree.
