Subject: [PATCH 3/3] arm64: boot: dts: ti: k3-am62l3-evm: enable WKUP UART wakeup from LPM
Date: Tue, 30 Dec 2025 20:51:42 -0600	[thread overview]
Message-ID: <20251230-wkup-uart-wakeup-v1-3-cd6e15f8d956@ti.com> (raw)
In-Reply-To: <20251230-wkup-uart-wakeup-v1-0-cd6e15f8d956@ti.com>

Change the status of the wkup_uart0_interconnect node to enabled. The
target-module node sets the UART SYSC and SYSS registers to allow wakeup
from WKUP UART in DeepSleep low power mode.
