Subject: [PATCH v4 0/2] Driver for Microchip digital potentiometers
Date: Tue, 22 Sep 2015 17:36:47 +0200	[thread overview]
Message-ID: <1442936209-27057-1-git-send-email-peda@lysator.liu.se> (raw)

From: Peter Rosin <peda@axentia.se>

This is the fourth attempt for a driver for these chips.

Thanks for review comments from Greg Kroah-Hartman, Crt Mori,
Daniel Baluta, Lars-Peter Clauson, Andreas Dannenberg and Peter
Meerwald. I think and hope I got it all sorted.

Changes since v3:
- Use i2c_smbus_read_word_swapped (Peter)
- Use devm_iio_device_register and drop the mcp4531_remove op (Peter)
- Add defines for a few magic numbers (Peter)
- Deduplicate channel params with a macro (Peter)
- Mention the i2c client address options (Peter)
- Whitespace and other trivial nits (Peter)

Changes since v2:
- Change naming from mcp4xxx_dpot to mcp4531 (Daniel)
- Added links to datasheet in commit message and source (Daniel)
- Rename from pot to potentiometer (Daniel, Crt)
- Use IIO_RESISTANCE instead of IIO_STEPS (Crt, Lars-Peter)
- Don't use wildcards in MAINTAINERS and point to the iio list (Crt)
- Avoid races by not caching values (Crt)
- Spell Microchip correctly (Andreas)

Changes since v1:
- Make it an IIO driver instead (Greg)
- Don't convolute the code with big obscure macros (Greg)
- Inline the bits from mcp4xxx_dpot.h that are actually used
  and drop that file (me)
- Better Changelog (Greg)

Cheers,
Peter
