Thanks for review comments from Greg Kroah-Hartman, Crt Mori, Daniel Baluta, Lars-Peter Clauson, Andreas Dannenberg, Peter Meerwald and Jonathan Cameron. I think and hope I got it all sorted. Changes since v5: - Use a symbolic name to index the cfg array (Lars-Peter) - Consolidate handling of MCP4xx1 and MCP4xx2 (me) Changes since v4: - Less convoluted changelog (Jonathan) - Use an index into an array of configs as dev_id (Jonathan) - Drop .address and use .channel (Jonathan) - Remove one layer of wrappers (Jonathan) - Provide a scale (Jonathan, Lars-Peter) 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 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 | 231 +++++++++++++++++++++++++++++++ 7 files changed, 267 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
