Subject: [PATCH 11/11] arm64: dts: ti: k3-j7200-mcu-wakeup: add VTM node
Date: Tue, 11 Oct 2022 18:17:27 -0500	[thread overview]
Message-ID: <20221011231727.8090-12-bb@ti.com> (raw)
In-Reply-To: <20221011231727.8090-1-bb@ti.com>

The j7200 supports a single Voltage and Thermal Management (VTM) device
located in the wakeup domain with three associated temperature monitors
located in various hot spots on the die.
