[PATCH v2 0/4] iio: adc: ad4695: new driver for AD4695 and similar ADCs

This is adding DT bindings and a new driver for the AD4695 and similar
devices. The plan is to implement quite a few more features, but this
is a complex chip so we're spreading out the work. To start with, we
have a reasonably complete DT binding and a very basic driver.

This work is being done in collaboration with Analog Devices Inc.,
hence they listed as maintainers rather than me. The code has been
tested on a Zedboard with an EVAL-AD4696FMCZ using the internal LDO,
an external reference and a variety of input channel configurations.
