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.
