    Subject[PATCH v2 0/8] gpio: exar: refactor the driver
    Date
    From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

    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

    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 (8):
    regmap: provide regmap_assign_bits()
    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()
