Hi Jonathan,

Instead of adding IIO_VAL_INT_H32_L32, I am thinking of adding IIO_VAL_FRACTIONAL_LONG
or IIO_VAL_FRACTIONAL_64 as the scale/exponent used for min/max range can be different
than the one used in resolution according to specification. 

I am planning to use read_avail for IIO_CHAN_INFO_PROCESSED using IIO_AVAIL_RANGE 
and this new IIO_VAL_FRACTIONAL_64 for min range,max range and resolution.
Instead of two values used in IIO_VAL_FRACTIONAL, IIO_VAL_FRACTIONAL_64 will use 4 values
val_high,val_low,and val2_high and val2_low.

Let me know if that is an acceptable solution.


Thanks,
Jyoti
