The tablet has a charger LED exposed on the top. This LED is controlled

Dang, I just noticed someone sent a similar driver recently, although I had this
one prepared for quite some time (since 2017) in my tree. I guess I should have
sent it earlier.
Please ignore.
Though the meaning of "recently" is a bit relative. The other work was sent in
a year ago. Here's a reference:

Hi,
I'm the author of the 'other' work. I don't know the full story here,
but I don't
mind someone else submitting this patch as his.
When I submitted the last patch, there was the proposal to use the
ledtrig-pattern instead
of sysfs entries. Also AXP209 has inverted CTRL bit.
Please read the the 'other' discussion.
Best regards,
Stefan Mavrodiev

Please take a look.
