Subject: [PATCH v3 07/11] arm64: dts: ti: k3-am64-main: add VTM node
Date: Mon, 31 Oct 2022 18:26:58 -0500 [thread overview]
Message-ID: <20221031232702.10339-8-bb@ti.com> (raw)
In-Reply-To: <20221031232702.10339-1-bb@ti.com>
The am64x supports a single VTM module which is located in the main
domain with two associated temperature monitors located at different hot
spots on the die.
