Subject: [PATCH 0/2] Add support for AD7293 Power Amplifier

The AD7293 is a Power Amplifier drain current controller containing 
functionality for general-purpose monitoring and control of 
current, voltage, and temperature, integrated into a single chip 
solution with an SPI-compatible interface.

Datasheet:
https://www.analog.com/media/en/technical-documentation/data-sheets/AD7293.pdf

This series of patches provide an initial implementation of the
driver with access from the userspace to the:
 - ADC channels (read raw values, set range, set offset)
 - DAC channels (set code, set offset)
 - Temperature sensing (read raw values, set offset)
 - Current sensing (read raw, set offset, set gain)
