Subject: [PATCH v3 10/11] arm64: dts: ti: k3-j721s2-mcu-wakeup: add VTM node
Date: Mon, 31 Oct 2022 18:27:01 -0500 [thread overview]
Message-ID: <20221031232702.10339-11-bb@ti.com> (raw)
In-Reply-To: <20221031232702.10339-1-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.
