Thanks for the hints. Now it compiles and the driver seems to work.
One thing I do not understand: It does not matter what channel I read
('in_voltage*_raw'), only interrupt 16 ('mxs-lradc-channel0') counts up.
Intended?
Or did I a mistake by adding interrupt numbers "<13 14 15 16 17 18 19 20 21 22
23 24 25>" to the corresponding device tree entry?
Regards,
Juergen
