dt-bindings: iio: adc: mediatek,mt6359-auxadc: add mt6323 PMIC AUXADC

2026-07-02T15:43:45+00:00

The MediaTek mt6323 PMIC includes an AUXADC used for battery voltage,
temperature, and other internal measurements. The IP block is not
register-compatible with mt6359.

Add the devicetree binding documentation and the associated header file
defining the ADC channel constants.

Also change the description to 'MT6350 series and similar' because
the binding already includes more than mt635x series PMICs.

Finally, add the MAINTAINERS entry for the header with ADC constants.

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.

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.
