Enabling sinc4 disables fir filters. Disabling sinc4 defaults back to both fir filters being enabled. Sinc4 filter center matches the configured sampling frequency. GPIO configuration now depends on the interrupt-names property. Leaving it blank results in probe error when there is an interrupt specified. Regards, Ibrahim Note: No sign-off tag for David as he was unreachable when the initial patch was sent. Changelog: 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 Ibrahim Tilki (3): iio: adc: add max11410 adc driver dt-bindings: iio: adc: add adi,max11410.yaml Documentation: ABI: testing: add max11410 doc .../ABI/testing/sysfs-bus-iio-adc-max11410 | 13 + .../bindings/iio/adc/adi,max11410.yaml | 174 +++ drivers/iio/adc/Kconfig | 13 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/max11410.c | 1051 +++++++++++++++++ 5 files changed, 1252 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-adc-max11410 create mode 100644 Documentation/devicetree/bindings/iio/adc/adi,max11410.yaml create mode 100644 drivers/iio/adc/max11410.c
