You prefixed your arrays with `tps65224` and that makes sense. However
you should also prefix the old ones with `tps6594` then.
This applies to the whole driver.

The comment is not adding anything, the name is clear and ARRAY_SIZE is
quite explicit.

There is an indentation missing on the content of the `for` loop.
