From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx> The ADS1119 is a precision, 16-bit, analog-to-digital converter (ADC) that features two differential or four single-ended inputs through a flexible input multiplexer (MUX), rail-to-rail input buffers, a programmable gain stage, a voltage reference, and an oscillator. Apart from normal single conversion, the driver also supports continuous conversion mode using a triggered buffer. However, in this mode only one channel can be scanned at a time. v3: bindings: - add avdd and dvdd supplies - add Reviewed-by: Conor Dooley <conor.dooley@xxxxxxxxxxxxx driver: - add MICRO constant on necessary places - add devm_regulator_bulk_get_enable() to handle avdd/dvdd supplies - add power down action with devm_add_action_or_reset() - add buffer setup functions - add iio_validate_scan_mask_onehot() to guarantee only one scan channels - add support to other triggers than only the adc irq - add device check to adc irq trigger to guarantee associating it only its own device - add a cached value for the config register - change ads1119_get_hw_datarate() return - change return location in read_raw() and write_raw() - change return location in ads1119_read_data() - change the scan buf to a local struct with correct size and alignment - change ads1119_update_config_reg() to ads1119_upd_cfg_reg() - fix over wrap in read_poll_timeout() - remove unnecessary goto label in ads1119_single_conversion() - remove unnecessary empty lines - remove scan mask from the driver state - remove ads1119_validate_gain() and call it inline in write_raw() - remove all ads1119_cmd functions and use i2c_smbus inline v2: https://lore.kernel.org/all/20240606163529.87528-1-francesco@xxxxxxxxxx/ bindings: - add diff-channels and single-channel - remove ti,gain and ti,datarate - more details on the patch changelog driver: - adaptation for the binding changes - changed i2c read/write to the device (not using regmap anymore, use FIELD macros) - more details on the patch changelog v1: https://lore.kernel.org/all/20240527154050.24975-1-francesco@xxxxxxxxxx/ João Paulo Gonçalves (2): dt-bindings: iio: adc: add ti,ads1119 iio: adc: ti-ads1119: Add driver .../bindings/iio/adc/ti,ads1119.yaml | 155 ++++ MAINTAINERS | 8 + drivers/iio/adc/Kconfig | 12 + drivers/iio/adc/Makefile | 1 + drivers/iio/adc/ti-ads1119.c | 839 ++++++++++++++++++ 5 files changed, 1015 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/adc/ti,ads1119.yaml create mode 100644 drivers/iio/adc/ti-ads1119.c -- 2.39.2
