(This is a re-send, with input subsystem maintainer added. Sorry,
for the extra noise, I did only send the v4 to the previous recipients
of v3, and didn't notice input subsystem was missing back then too.
Thank you wens for pointing it out.)

This series implements r_lradc (low res ADC) support for A83T.

This is a continuation of v3 patch series from 2017 by Ziping Chen. I've
rebased it on top of linux-next and changed the compatibe string as
requested back then.[1]

There was some talk of iio based lradc driver back then[2], but noone
stepped forward to make it. Let's finish this series, so that it's
at least possible to add support for tablet keys on various A83T tablets
as that's the main use of lradc module.

Please take a look, and apply the patches if you have no objections.

regards,
  Ondrej Jirman
