Subject: [PATCH v2 0/4] iio: mark scan_timestamp as __private

Changes in v2:

- Droped patches 1,2.
- DLN2-ADC: zero full struct instead of just the padding
- MAX1363: add the data buffer in the iio_priv()
- SSP_IIO: calculate always the timestamp
- iio_push_to_buffers_with_timestamp(): mark the access of the
  indio_dev->scan_timestamp as ACCESS_PRIVATE()

---
v1: https://lore.kernel.org/linux-iio/20241130002710.18615-1-vassilisamir@gmail.com/

The scan_timestamp value of the struct iio_dev, even though is an
internal variable, it is being used in some drivers. To avoid any
unwanted overwrites of this value, create a getter and when all the
drivers are converted, mark the variable as __private.

The patch is an RFC because the added value might not be considered
high enough by someone to be implemented and/or it might need to be
done in a different way since it touches multiple drivers.
Vasileios Amoiridis (4):
  iio: adc: dln2-adc: zero full struct instead of just the padding
  iio: adc: max1363: make use of iio_is_soft_ts_enabled()
  iio: common: ssp_sensors: drop conditional optimization for simplicity
  iio: core: mark scan_timestamp as __private
