Iâve tested this series with Odroid N2 and Khadas VIM3, X96-Max. Patches to add
support for VIM3/X96-max will be submitted once the driver is merged.

VIM3:~ # dmesg | grep thermal
[    0.046375] thermal_sys: Registered thermal governor 'step_wise'

VIM3:~ # cat /sys/devices/virtual/thermal/thermal_zone0/temp
51300

VIM3:~ # cat /sys/devices/virtual/thermal/thermal_zone1/temp
52800
