Right, so I guess that some part of the:

modprobe i2c-dev
i2cset -y -f 6 0x34 0x82 0xf0
i2cset -y -f 6 0x34 0x84 0xf0

Workaround which you have been using somehow sticks around even after a
power-cycle.

These tablets often have a mode where they show an animation when charging
while turned off.

Can you try turning the tablet off without the charger connected and then plug
in the charger and see if you get such an animation? If you do then after that
boot 
with 'axp288_adc' still blacklisted and then dump the 2 registers again.

If that does not make any change, then I wonder what happens if you do load the
axp288_adc driver and then try to charge the tablet ? It sounds to me like that
should just work. IOW it seems that your workaround maybe is no longer needed ?

Another interesting data point would be if you can unplug the battery, or keep
the tablet on till it powers off due to the battery being dead (check it does
not power-up again without charging) and then after that boot with 'axp288_adc'
still blacklisted and then dump the 2 registers again, so that we know we
really have the firmware set values and not values previously set by the
workaround sticking over a reboot.

Talking about the workaround. I assume you have disabled any systemd units you
have
written to do this automatically?
