Subject: [PATCH v3 0/2] Driver for Microchip digital potentiometers

From: Peter Rosin <peda@...ntia.se>

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

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

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
- Don't convolute the code with big obscure macros
- Inline the bits from mcp4xxx_dpot.h that are actually used
  and drop that file
- Better Changelog

Cheers,
Peter
