Subject: [PATCH v4 0/7] gpio: exar: refactor the driver
From: Bartosz Golaszewski <bgolaszewski@...libre.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
v2 -> v3:
- drop the regmap helper from series
v3 -> v4:
- renamed the regmap variable to 'regmap' as leaving the old name caused me
to miss an assignment leading to a crash (culprit spotted by Andy Shevchenko)
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()
