Message

Marcelo Schmitt March 14, 2025, 5:17 p.m. UTC

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.
