Hello,

This series add support for adaq4370-4 (2MSPS) and adaq4380-4 (4MSPS)
which are quad-channel precision data acquisition signal chain μModule
solutions compatible with the ad738x family, with the following differences:

- configurable gain in front of each 4 adc
- internal reference is 3V derived from refin-supply (5V)
- additional supplies

This series depends on [1] which fix several supplies issues
