ad525x_dpot: new driver for AD525x digital potentiometers
This driver supports the non-volatile digital potentiometers via I2C: AD5258, AD5259, AD5251, AD5252, AD5253, AD5254, and AD5255 It provides a sysfs interface to each device for reading/writing which is documented in Documentation/misc-devices/ad525x_dpot.txt.
