[PATCH v1 0/4] AD7949 Fixes

From: Liam Beguin
Date: Thu Jul 08 2021 - 19:56:43 EST

While working on another series[1] I ran into issues where my SPI
controller would fail to handle 14-bit and 16-bit SPI messages. This
addresses that issue and adds support for selecting a different voltage
reference source from the devicetree.

This is base on a series[2] that seems to not have made it all the way,
and was tested on an ad7689.
