Subject: [PATCH V3 1/2] arm64: dts: ti: k3-am62-wakeup: Introduce RTC node
Date: Mon, 20 Mar 2023 11:51:22 -0500 [thread overview]
Message-ID: <20230320165123.80561-2-nm@ti.com> (raw)
In-Reply-To: <20230320165123.80561-1-nm@ti.com>
Introduce digital RTC node in wakeup domain. Even though this has
no specific battery backup supply, this on-chip RTC is used in
cost-optimized board designs as a wakeup source.
