hwmon: Add MCP3021 ADC driver Add I2C driver for MCP3021 that is an ADC chip from Microchip. The MCP3021 is a successive approximation A/D converter (ADC) with 10-bit resolution. The driver export the value of Vin to sysfs, the voltage unit is mV. Through the sysfs interface, lm-sensors tool can also display Vin voltage.

converter (ADC) with 10-bit resolution. The MCP3221 has 12-bit resolution.
These devices provide one single-ended input with very low power consumption.
Communication to the MCP3021/MCP3221 is performed using a 2-wire I2C
compatible interface. Standard (100 kHz) and Fast (400 kHz) I2C modes are
available. The default I2C device address is 0x4d (contact the Microchip
factory for additional address options).
