I can't find the temperature measured by the PTC resistor of my Renata battery. Is the reading of the temperature value available somewhere? If so, could this please also be documented here?
Answer: this has not yet (as of kernel version 6.11.2) been implemented.
Also: the maximum charging current seems to be ignored, I find the following (Armbian 6.6.52 kernel):
root@nas:~# od --endian=big -td4 < /sys/firmware/devicetree/base/battery/constant-charge-current-max-microamp 0000000 1400000 0000004
However:
root@nas:~# cat /sys/class/power_supply/rk817-battery/constant_charge_current_max 1000000
Answer: this is a hardware limitation, I have updated the Wiki-page accordingly.
