From: Linus Walleij Date: Wed, 15 Dec 2021 17:39:52 +0000 (+0100) Subject: ARM: dts: ux500: Add battery thermal zones and NTCs X-Git-Tag: howlett/maple/20220722_2~947^2~42^2~3 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fb7f1727fdf83931eab2bd9bc0978133bf231a54;p=users%2Fjedix%2Flinux-maple.git 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.
