              ^^^^^^^
This function is not beautiful.  I think since you're changing it from
being tps6594 specific, maybe you want to rename a bunch of stuff.

Either 1) pass both the array and the size or 2) just use tps->chip_id
to determine both the array and the arrays_size.  Passing the array and
then determining which array was passed by looking at the type is ugly.
