This patch series extends the ad4000 driver to support SPI offloading. In addition to that, ad4000 IIO documentation is expanded to: - list PulSAR parts supported by the ad4000 driver. - describe some characteristics of AD4000 IIO device. - describe changes when SPI offload is being used. The proposed changes were tested with AD7687 and ADAQ4003 on CoraZ7 setup running Linux built from IIO testing branch.
