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