This patch series introduces some new features, improvements, and fixes for the AD7768-1 ADC driver. The goal is to support all key functionalities listed in the device datasheet, including filter mode selection, common mode voltage output configuration and GPIO support. Additionally, this includes fixes for SPI communication and for IIO interface, and also code improvements to enhance maintainability and readability. --- Changes in v3: * Fixed irregular or missing SoBs. * Moved MOSI idle state patch to the start of the patch, as the other fix. * fixed dt-binding errors. * Trigger-sources is handled in a different way, as an alternative to sync-in-gpio. (this way we avoid breaking old applications). * VCM output is controlled by the regulator framework. * Added a second regmap for 24-bit register values. * Add new preparatory patch replacing the manual attribute declarations for the read_avail from struct iio_info. * included sinc3+rej60 filter type. * Addressed review comments, see individual pacthes. * Link to v2: https://lore.kernel.org/linux-iio/cover.1737985435.git.Jonathan.Santos@xxxxxxxxxx/T/#u Changes in v2: * Removed synchronization over SPI property and replaced it for trigger-sources. * Added GPIO controller documentation. * VCM output control changed from an IIO attribute to a devicetree property (static value). * Converted driver to use regmap and dropped spi_read_reg and spi_write_reg pacthes. * replaced decimation_rate attribute for oversampling_ratio and dropped device specific documentation patch. * Added low pass -3dB cutoff attribute. * Addressed review comments, see individual pacthes. * Link to v1: https://lore.kernel.org/linux-iio/cover.1736201898.git.Jonathan.Santos@xxxxxxxxxx/T/#t --- Jonathan Santos (13): iio: adc: ad7768-1: set MOSI idle state to prevent accidental reset dt-bindings: iio: adc: ad7768-1: add trigger-sources property dt-bindings: iio: adc: ad7768-1: Document GPIO controller dt-bindings: iio: adc: ad7768-1: document regulator provider property Documentation: ABI: add wideband filter type to sysfs-bus-iio iio: adc: ad7768-1: remove unnecessary locking iio: adc: ad7768-1: convert driver to use regmap iio: adc: ad7768-1: add regulator to control VCM output iio: adc: ad7768-1: add multiple scan types to support 16-bits mode iio: adc: ad7768-1: add support for Synchronization over SPI iio: adc: ad7768-1: replace manual attribute declaration iio: adc: ad7768-1: add filter type and oversampling ratio attributes iio: adc: ad7768-1: add low pass -3dB cutoff attribute Sergiu Cuciurean (4): iio: adc: ad7768-1: Fix conversion result sign iio: adc: ad7768-1: Add reset gpio iio: adc: ad7768-1: Move buffer allocation to a separate function iio: adc: ad7768-1: Add GPIO controller support Documentation/ABI/testing/sysfs-bus-iio | 2 + .../bindings/iio/adc/adi,ad7768-1.yaml | 59 +- drivers/iio/adc/ad7768-1.c | 1068 ++++++++++++++--- 3 files changed, 949 insertions(+), 180 deletions(-) base-commit: 5de07b8a24cf44cdb78adeab790704bf577c2c1d prerequisite-patch-id: 8b531bca46f7c7ea1c0f6d232d162fd05fda52f7 -- 2.34.1
