AD4130-8 is an ultra-low power, high precision, measurement solution for low bandwidth battery operated applications. The fully integrated AFE (Analog Front-End) includes a multiplexer for up to 16 single-ended or 8 differential inputs, PGA (Programmable Gain Amplifier), 24-bit Sigma-Delta ADC, on-chip reference and oscillator, selectable filter options, smart sequencer, sensor biasing and excitation options, diagnostics, and a FIFO buffer. V1 -> V2 * add kernel version to ABI file * merge ABI patch into driver patch * make copyright header similar to other drivers * rearrange includes * use units.h defines where possible and add unit sufix to SOFT_RESET_SLEEP define * remove ending comma to last members of enums / lists * remove unused FILTER_MAX define * use BIT macro for PIN_FN_* * rearrange SETUP_SIZE definition * group bools in ad4130_state and ad4130_chan_info * put scale_tbls definition on one line * remove newline before reg size == 0 check * put mask used as value in a variable * remove useless ret = 0 assignment * make buffer attrs oneline * use for_each_set_bit in update_scan_mode * use if else for internal reference voltage error checking * inline reference voltage check * check number of vbias pins * remove .has_int_pin = false * remove avail_len for IIO_AVAIL_RANGE * remove useless enabled_channels check in unlink_slot * remove unused AD4130_RESET_CLK_COUNT define * only call fwnode_handle_put for child in case of error * default adi,reference-select to REFIN1 * default adi,int-ref-en to false * of_irq_get_byname -> fwnode_irq_get_byname * P1 -> P2 as interrupt pin options * add missing comma in db3_freq_avail init * cast values to u64 to make math using units.h work * add datasheet reference to IRQ polarity * add comment about disabling channels in predisable * add part number prefix find_table_index * return voltage from get_ref_voltage * add datasheet reference for internal reference voltage selection * add comment explaining AIN and GPIO pin sharing * parse channel setup before parsing excitation pins * only validate excitation pin if value is not off * use FIELD_PREP for bipolar and int_ref_en * put devm_regmap_init call on one line * introduce a slot_info struct to contain setup_info for each slot * enable internal reference automatically if needed * decide mclk sel based on adi,ext-clk-freq and adi,int-clk-out * dt-bindings: use internal reference explicitly * dt-bindings: set type for adi,excitation-pin-0 * dt-bindings: set $ref for adi,vbias-pins * dt-bindings: remove minItems from interrupts property * dt-bindings: remove adi,int-ref-en default value * dt-bindings: remove adi,bipolar default value * dt-bindings: inline adi,int-ref-en description * dt-bindings: default adi,reference-select to REFIN1 * dt-bindings: clean up description for diff-channels and adi,reference-select * dt-bindings: add more text to interrupt-names description * dt-bindings: turn interrupt-names into a single string * dt-bindings: add maxItems to adi,vbias-pins V2 -> V3 * dt-bindings: add interrupt controller include to example * dt-bindings: remove $ref in diff-channels Cosmin Tanislav (2): dt-bindings: iio: adc: add AD4130 iio: adc: ad4130: add AD4130 driver .../ABI/testing/sysfs-bus-iio-adc-ad4130 | 36 + .../bindings/iio/adc/adi,ad4130.yaml | 264 +++ MAINTAINERS | 8 + drivers/iio/adc/Kconfig | 13 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/ad4130.c | 2078 +++++++++++++++++ 6 files changed, 2400 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-bus-iio-adc-ad4130 create mode 100644 Documentation/devicetree/bindings/iio/adc/adi,ad4130.yaml create mode 100644 drivers/iio/adc/ad4130.c -- 2.35.3
