Subject: [PATCH v4 0/3] Re-add filter_type/filter_mode

Better document sysfs ABI for ADC digital filter configuration.
Also update ad4130 driver to support the standardized IIO ABI for digital filter
configuration.

Change log v3 -> v4
- Renamed in_voltage-voltage_filter_mode_available to
  in_voltage-voltage_filter_type_available instead of just removing the mode
  variant from sysfs-bus-iio.
- Added comment about backwards compatibility near ad4130 filter attribute
  declarations.
- Reordered patches so attributes are documented before use.
- Minor re-word of in_voltage-voltage_filter_mode_available text in
  sysfs-bus-iio-adc-ad4130 to make it more generic.
- Picked up review tags.

Change log v2 -> v3
- Added in_voltageY-voltageZ_filter_type to main IIO ADI doc too.
- Added filter_type attributes to ad4130 driver so it also supports the
  standardized ABI for digital filter configuration.
- No longer dropping AD4130 specific filter_type_available options from sysfs-bus-iio.
- Re-add sysfs-bus-iio-adc-ad4130 just mentioning the ABI at sysfs-bus-iio instead
  of repeating the doc.

Change log v1 -> v2
- Split into 3 patches.
- Re-added sysfs-bus-iio-adc-ad4130 to keep filter_mode separate from filter_type.
- Removed in_voltage-voltage_filter_mode_available from sysfs-bus-iio.
- Added deprecation notes in sysfs-bus-iio-adc-ad4130 asking to use filter_type
  for new drivers and referencing sysfs-bus-iio.
- Improved commit message with explanation about use of filter type attributes.
- Dropped AD4130 specific filter_type_available options from sysfs-bus-iio.
