[PATCH v3 0/2] iio: potentiometer: Add driver support for AD5110

[Mugilraj Dhavachelvan]

Add dt-bindings and driver support for AD5110, a Nonvolatile 
Digital Potentiometer.

Changes since v2:
 - Drop Redundant blank lines
 - Add missed prefix name
 - Add comma to non terminator line
 - Add missed error code return when ret < 0
 - Explanation for msleep(20)
 - Change to IIO_DEVICE_ATTR_RW()
 - Remove comma for terminator line
 - Drop data->cfg dead code since I'm using probe_new()

Changes since v1: 
 - Drop 'shared_by_type' since it's a single channel
 - Add error check for i2c read/write data bytes
 - Simplified calculation for tolerance
 - Add shift for eeprom wiper pos read
 - Change new custom ABI to existing ABI 
 - Allow top-scale mode by writting max_pos to val
