I just wanted to convert the driver to using simpler IDA API but ended up
quickly converting it to using regmap. Unfortunately I don't have the HW
to test it so marking the patches that introduce functional change as RFT
and Cc'ing the original author.

v1 -> v2:
- add new regmap helper: regmap_assign_bits()
- fix lvl vs sel register access
- set value in direction_output callback

v2 -> v3:
- drop the regmap helper from series

Note: I didn't use the fancy method of offset calculation Andy and David
suggested because this series broke the driver according to Jan - let's
get it right before we modify it any more. I found a couple problems that
could maybe cause the crash. Jan: could you give it another spin?

Bartosz Golaszewski (7):
  gpio: exar: add a newline after the copyright notice
  gpio: exar: include idr.h
  gpio: exar: switch to a simpler IDA interface
  gpio: exar: use a helper variable for &pdev->dev
  gpio: exar: unduplicate address and offset computation
  gpio: exar: switch to using regmap
  gpio: exar: use devm action for freeing the IDA and drop remove()
