[PATCH v4 0/7] iio: light: ltr501: Add ltr329 support

[Esben Haabendal <esben@geanix.com>]

The LiteON LTR-329ALS-01 chip is similar to the LTR-303ALS-01, except for
interrupt support and related registers, which LTR-329ALS-01 does not have.

Changes in v4:
- Split the duplicate error message removal into separate patch.
- Removed uneeded enum =0 assignment.
- Use dev_err_probe() instead of plain dev_err().
- Link to v3: https://patch.msgid.link/20260804-liteon-ltr329-v3-0-c6b768c7c745@geanix.com

Changes in v3:
- Removed duplicated error message on devm_request_threaded_irq() failure.
- Added Fixes: and Cc: stable tags to fix for error handling of
  devm_request_threaded_irq() failure.
- Added no_irq_support boolean to simplify checking for chip irq support.
- Moved check for no_irq_support from ltr501_read_intr_prst() and
  ltr501_write_intr_prst() to callers. Note: event functions are not
  registered for no_irq_support devices.
- Moved #include <linux/array_size.h> into its place according to
  alphabetical sorting order (although the rest is not really wel sorted).
- Restored alphanumerical ordering of compatible list in bindings
  documentation.
- Ordered device arrays and enum values according to alphanumerical sorting
  order.
- Link to v2: https://patch.msgid.link/20260715-liteon-ltr329-v2-0-d18af55edab5@geanix.com

Changes in v2:
- Fixed error handling when irq is defined for a chip that does not support
  irq, powering the chip down again.
- Added simlar fix to error handling of devm_request_threaded_irq() error
  handling, powering the chip down again on failure.
- Added explicit #include <linux/array_size.h>.
