[PATCH v3 0/2] iio: adc: ad7173: add calibration support to chip family

[Guillaume Ranquet]

Calibration on the ad7173 family is the same as on the ad7192 family of
chips and mostly uses the ad_sigma_delta common code.

Signed-off-by: Guillaume Ranquet <granquet@xxxxxxxxxxxx>

Changes in v3:
- Small fixes to the ABI documentation of sigma_delta
- Move the system calibration mode to the ad7173_channel to avoid yet
  another allocation.
- Link to v2: https://lore.kernel.org/r/20241127-ad411x_calibration-v2-0-66412dac35aa@xxxxxxxxxxxx

Changes in v2:
- Add a common ad sigma delta ABI documentation to describe calibration
  nodes that are common in the sigma delta family.
- Link to v1: https://lore.kernel.org/r/20241115-ad411x_calibration-v1-1-5f820dfb5c80@xxxxxxxxxxxx
