2017-01-22	iio: potentiometer: mcp4531: Export OF device ID table as module aliases	Javier Martinez Canillas
	The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it.

2016-07-03	iio: potentiometer: mcp4531: Add support for MCP454x, MCP456x, MCP464x and ↵	Florian Vaussard
	MCP466x This patch adds support for MCP454x, MCP456x, MCP464x and MCP466x parts. The main difference with currently supported parts (MCP453x and alike) is the addition of a non-volatile memory in order to recall the wiper setting at power-on. This feature is currently not supported and only the volatile memory is used to set the wiper.

2016-04-03	iio: potentiometer: mcp4531: use pointer to access model parameters	Slawomir Stepien
	Use const pointer to element from model configuration array rather then array index, as it will not change anyway. Signed-off-by: Slawomir Stepien <sst@poczta.fm> Signed-off-by: Peter Rosin <peda@axentia.se> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
2016-02-27	iio: convert to common i2c_check_functionality() return value	Matt Ranostay
	Previously most drivers that used a i2c_check_functionality() check condition required various error codes on failure. This patchset converts to a standard of -EOPNOTSUPP Signed-off-by: Matt Ranostay <mranostay@gmail.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
