Hmm, suspend again for 15s.

[ 105.520634] PM: suspend exit
[ 105.540206] ts_ref 1591097307780181385, ts 2861700000, sample_time
1591097310641881385
[ 105.548416] ktime_get_real_ns: 1591097322928175385
CLOCK_REALTIME isn't ready in the resume function. I think we need to link
it to CLOCK_BOOTTIME (Which ticking under suspend) instead.
With latest patch it seems to me the time reported is now monotonic so it seems
correct. What is the clocktype you set? you can check it in:
/sys/bus/iio/devices/iio:device<x>/current_timestamp_clock
default: realtime
In the dump above the ktime_get_real_ns(first fifo dump after suspend) -
ts_ref + ts is = 12,286294 sec...
