iio: potentiometer: mcp4531: Add support for MCP454x, MCP456x, MCP464x and MCP466x 2016-07-03T11:39:58+00:00 Florian Vaussard florian.vaussard@gmail.com 2016-06-30T07:34:48+00:00 294ea6f3a162fc0091e80170b8176bf326962d1c 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.
