Subject: [PATCH RESEND V11 4/4] arm64: dts: imx: add i.MX8QXP thermal support
Date: Wed, 10 Apr 2019 07:43:31 +0000 [thread overview]
Message-ID: <1554881866-26333-4-git-send-email-Anson.Huang@nxp.com> (raw)
In-Reply-To: <1554881866-26333-1-git-send-email-Anson.Huang@nxp.com>
Add i.MX8QXP CPU thermal zone support.
Signed-off-by: Anson Huang <Anson.Huang@nxp.com>
---
Changes since V10:
- remove property "imx,sensor-resource-id" and put HW resource ID inside each
thermal-sensors' phandle argument.
