Hi Guenter.
sun4i-gpadc-iio.c uses built-in four-channel ADC that is dedicated to
RTP (resistive touch panel). It also can be used as a general purpose
10-bit ADC, but it's a different piece of hardware inside SoC along with
LRADC.

Some Allwinner SoCs like A13, A20 or T2 are equipped with two-channel
low rate (6 bit) ADC that is often used for extra keys. There's a
driver
for that already implementing standard input device, but it has these
limitations: 1) it cannot be used for general ADC data equisition,
and
2) it uses only one LRADC channel of two available.
This driver provides basic hwmon interface to both channels of LRADC
on
such Allwinner SoCs.

Before even going to check actual driver, please read
https://www.kernel.org/
doc/html/latest/process/submitting-patches.html in detail.
Just few basic things to fix first:
1. subject doesn't conform to rules
2. send patch to maintainers and mailing lists (use
scripts/get_maintainer.pl)
I only got the copy sent directly to me. Anyway, how is this different
to
the driver in drivers/iio/adc/sun4i-gpadc-iio.c ?
