This is a Linux industrial I/O (IIO) subsystem driver, targeting Resolver-to-Digital Converters. The industrial I/O subsystem provides a unified framework for drivers for many different types of converters and sensors using a number of different physical interfaces (i2c, spi, etc). See IIO for more information.

Configure kernel with “make menuconfig” (alternatively use “make xconfig” or “make qconfig”)
