DS3502 is a 7 bit Nonvolatile Digital Potentiometer. Changes since v2: 1. Addressed Andy Shevchenko comments. 2. Adding device name in Kconfig file. 3. Spliting up of patch into 3 patchs. 4. Adding channel info into ds1803_cfg in separate patch. 5. Dropping the use of enum in firmware data instead using previous pointer method for accessing device specific data. 6. Separate patch for using firmware provided data instead of id->driver_data. 7. Adding DS3502 support in separate patch. Changes since v1: 1. Fixes the alignment to match the open parenthesis in separate patch. 2. Adding available functionality for ds1803 driver in separate patch. 3. Moving maxim_potentiometer members into ds1803_cfg structure. 4. Droping of the INFO_ENABLE channel type. 5. Firmware entry with data is used instead of id->driver_data to to retrieve the chip specific data.
