I did a systemupgrade (pacman -Syu) after quite a time. In this upgrade the kernel was updated as well.
After this my adc did not work anymore
$ dmesg gives:
$this->bbcode_second_pass_code('', '
[ 2.020000] iio iio:device0: Resolution used: 10 bits
[ 2.030000] iio iio:device0: ADC Touch screen is disabled.

')
and
$this->bbcode_second_pass_code('', '
[root@weatherstation ~]# ll /sys/bus/iio/devices/
total 0
')
was not very helpfull. It's about a Arietta G25
Who can help?
