For the series:

Tested-by: Konrad Dybcio <konrad.dybcio@...aro.org> # SM8350 PDX215

Thanks a lot for working on this!

One thing, /sys/class/power_supply/qcom-battmgr-usb/input_current_limit
is stuck at zero and so is the current_now as a result (the voltage
readout is 5V + some noise, so that looks good), but I don't see any
SET paths for it in the driver, so I suppose that's what the firmware
default is?
