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 Peter Rosin (2): iio: resistance: Document that resistance can be output iio: mcp4531: Driver for Microchip digital potentiometers Documentation/ABI/testing/sysfs-bus-iio | 2 + MAINTAINERS | 6 + drivers/iio/Kconfig | 1 + drivers/iio/Makefile | 1 + drivers/iio/potentiometer/Kconfig | 20 ++++ drivers/iio/potentiometer/Makefile | 6 + drivers/iio/potentiometer/mcp4531.c | 200 +++++++++++++++++++++++++++++++ 7 files changed, 236 insertions(+) create mode 100644 drivers/iio/potentiometer/Kconfig create mode 100644 drivers/iio/potentiometer/Makefile create mode 100644 drivers/iio/potentiometer/mcp4531.c -- 1.7.10.4
