Subject: [PATCH v5] arm64: dts: ls1088a: add one more thermal zone node
Date:   Thu, 11 Apr 2019 16:32:36 +0800
Message-Id: <20190411083236.9377-1-andy.tang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Ls1088a has 2 thermal sensors, core cluster and SoC platform. Core cluster
sensor is used to monitor the temperature of core and SoC platform is for
platform. The current dts only support the first sensor.
This patch adds the second sensor node to dts to enable it.

---
v5:
	- update the thermal zone name due to the length limitation
	- remove cooling map in platform zone
v4:
	- use hyphen instead of underscore in node name
v3:
	- use more descriptive name for each zone
v2:
	- Add more information about sensors to description
