The tablet has a charger LED exposed on the top. This LED is controlled
by AXP813 PMIC. Add support for enabling the LED and using it either
for charging indication (handled by PMIC automatically) or for other uses
via user control.

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
