Subject: [PATCH v2 4/6] arm64: dts: ti: k3-j721s2-mcu-wakeup: add VTM node
Date: Thu, 19 Jan 2023 18:30:49 -0600 [thread overview]
Message-ID: <20230120003051.9100-5-bb@ti.com> (raw)
In-Reply-To: <20230120003051.9100-1-bb@ti.com>
The j721s2 supports a single Voltage and Thermal Management (VTM) device
located in the wakeup domain with seven associated temperature monitors
located in various hot spots on the die.
