Changelog:
since v7:

  - dtbinding: specify 2 items for interrupt-names
  - dtbinding: reorder required block

since v6:
  - don't require avdd supply if not needed

since v5:
  - allow user to specify both interrupt pins
  - keep irq info in max11410_state struct and use irq by name
  - get irqs by fwnode_get_irq_byname
  - don't allocate trigger when no irq supplied
  - fix deadlock condition in write_raw
  - minor style fixes
  - fix devicetree binding errors reported by dt_binding_check
  - convert module license to GPL as suggested by checkpatch

since v4:
  - add in_voltage_filter2_notch_{center,en} attrs for sinc4 filter
  - add ABI documentation for filter sysfs
  - check interrupt-names property for configuring gpio of max11410
  - remove hardwaregain property
  - add scale_available property for channes using PGA
  - separate vref regulator error -ENODEV from other errors
  - don't register trigger if no irq specified
  - style fixes

since v3:
  - prefix defines with MAX11410_
  - group vref regulators
  - use builtin iio_validate_scan_mask_onehot
  - validate iio trigger
  - move scan data into state struct
  - require vrefn regulator in DT if used by any channel
  - don't require irq for triggered buffer
  - remove filter sysfs attr and ABI documentation
  - add in_voltage_filter[0-1]_notch_{center,en} attrs

since v2:
  - remove bit position shifting, use field_prep instead
  - reduce the amount of reg writes in max11410_configure_channel
  - add error checking in max11410_parse_channels
  - remove some unneeded blank lines and minor style fixes
  - remove scan data assignment in max11410_trigger_handler
