[PATCH 1/2] ARM: dts: ux500: Add battery thermal zones and NTCs
Linus Walleij
linus.walleij at linaro.org
Fri Feb 4 16:25:06 PST 2022
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.
