dt-bindings: iio: adc: ad7768-1: add trigger-sources property

2025-06-26T18:32:53+00:00

In addition to GPIO synchronization, The AD7768-1 also supports synchronization over SPI, which use is recommended when the GPIO cannot provide a pulse synchronous with the base MCLK signal. It consists of looping back the SYNC_OUT to the SYNC_IN pin and send a command via SPI to trigger the synchronization. Introduce the 'trigger-sources' property to enable SPI-based synchronization via SYNC_OUT pin, along with additional optional entries for GPIO3 and DRDY pins. Also create #trigger-source-cells property to differentiate the trigger sources provided by the ADC. To improve readability, create a adi,ad7768-1.h header with the macros for the cell values. While at it, add description to the interrupts property.

dt-bindings: iio: adc: adi,ad7606: add SPI offload properties

2025-04-22T18:10:01+00:00

Add #trigger-source-cells property to allow the BUSY output to be used as a SPI offload trigger source to indicate when a sample is ready to be read. Macros are added to adi,ad7606.h for the cell values to help with readability since they are arbitrary values.

iio: adc: ad4695: move dt-bindings header

2024-12-07T17:47:58+00:00

Move the dt-bindings header file to the include/dt-bindings/iio/adc/ directory. ad4695 is an ADC driver, so it should be in the adc/ subdirectory for better organization. Previously, it was in the iio/ subdirectory.
