Subject: [PATCH V2 4/4] arm64: dts: imx8mm: Add thermal zone support
Date: Fri, 28 Feb 2020 10:53:33 +0800 [thread overview]
Message-ID: <1582858413-11906-4-git-send-email-Anson.Huang@nxp.com> (raw)
In-Reply-To: <1582858413-11906-1-git-send-email-Anson.Huang@nxp.com>
Add thermal zone and tmu node to support i.MX8MM thermal
driver, ONLY cpu thermal zone is supported, and cpu cooling
is also added.
