Subject: [PATCH 0/9] Add support for Software mode on AD7606's iio backend
 driver

This series adds the support for software mode when the ADC is used in
iio_backend mode.
The bus access is based on Angelo's ad3552 implementation, that is we
have a particular compatible for the backend (here axi-adc) version
supporting the ad7606's register writing, and the ad7606 is defined as a
child node of the backend in the devicetree.
Small changes are added to make the code a bit more straightforward to
understand, and more compact.
