[PATCH v2 0/5] Add support for AD4129-4/8, AD4130-4, and AD4131-4/8

[Jonathan Santos]

This patch series extends the AD4130 driver to support additional variants
in the AD4130 family: AD4129-4/8, AD4130-4, and AD4131-4/8.

The series introduces a chip info architecture to handle device-specific
differences. The AD4129 series provides 16-bit resolution with FIFO
support, while the AD4131 series offers 24-bit resolution but without
FIFO capability, requiring triggered buffer implementation. The 4-channel
variants feature reduced analog inputs, fewer GPIOs, and sparse pin
mappings.

Changes in v2:
* Add patch documenting the interrupts property.
* Add patch for the SPI id table, moving its content from the chip info 
  patch.
* Addressed other minor suggestions. See individual patches.
* Link to v1: https://lore.kernel.org/linux-iio/cover.1772078999.git.Jonathan.Santos@xxxxxxxxxx/T/#t/
