[PATCH v2 0/4] iio: adc: ad7768-1: add SPI offload support and fixes

[Jonathan Santos <Jonathan.Santos@analog.com>]

This series adds SPI offload support to the AD7768-1 driver and includes
fixes for one-shot mode operation and IRQ management discovered during
development and testing.

---
Changes in v2:
* Refactor "fix one-shot mode data acquisition" patch and keep it for backporting
  to older kernel versions.
* Instead of restricting the one-shot mode for some filter types, remove
  it completely and guarantee the device is always in continuous 
  conversion mode.
* Add "disable IRQ autoenable" patch to fix an old CPU usage issue and to avoid
  unnecessary interrupts when buffering data in offload mode.
* Addressed other review comments and kernel test robot reports, see individual patches.
* Link to v1: https://lore.kernel.org/linux-iio/cover.1769889074.git.Jonathan.Santos@analog.com/T/#t/
