From fb7f1727fdf83931eab2bd9bc0978133bf231a54 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 15 Dec 2021 18:39:52 +0100 Subject: ARM: dts: ux500: Add battery thermal zones and NTCs Add the thermal zones and thermistors used by the battery charging code to the device tree so the charger code can look up and poll the thermal zone for battery temperature.
