This series adds a new driver for the Analog Devices Inc. AD7625,
AD7626, AD7960, and AD7961. These chips are part of a family of
LVDS-based SAR ADCs. The initial driver implementation does not support
the devices' self-clocked mode, although that can be added later.

One aspect that is still uncertain is whether there should be a
devicetree property indicating if the DCO+/- pins are connected, so
specific feedback on that is appreciated.

The devices make use of two offset PWM signals, one to trigger
conversions and the other as a burst signal for transferring data to the
host. These rely on the new PWM waveform functionality being
reviewed in [1].

This work is being done by BayLibre and on behalf of Analog Devices
Inc., hence the maintainers are @analog.com.

Special thanks to David Lechner for his guidance and reviews.

I forgot to actually include:
