Subject: [PATCH v2 0/5] iio: adc: ad7380: fix several supplies issues

Hello,

This series tries to fix several issues found on the ad7380 driver about
supplies:

- vcc and vlogic are required, but are not retrieved and enabled in the
probe function
- ad7380-4 is the only device from the family that does not have internal
reference and uses REFIN instead of REFIO for external reference.

driver, bindings, and doc are fixed accordingly

Signed-off-by: Julien Stephan <jstephan@...libre.com>

Changes in v2:
- Fix kernel test robot warning about variable uninitialized when used [1]
- drop commit removing supply description in bindings
- after discussion on [2] we decided to add refin supply here, as it
  will be needed in the futur

- Link to v1: https://lore.kernel.org/r/20241007-ad7380-fix-supplies-v1-0-badcf813c9b9@baylibre.com
