iio: types: add IIO_VOLUMEFLOW channel typeAdd a new IIO channel type for liquid volumetric flow sensors. Theunit exposed via the standard _scale attribute is cubic metres persecond (m^3/s), following the SI convention used by the other IIOchannel types.Update iio-core's name table, the iio_event_monitor whitelist andthe sysfs-bus-iio ABI document to match. The new _scale attribute isfolded into the existing shared _scale block; only the per-type _rawneeds a fresh entry.Signed-off-by: Wadim Mueller Reviewed-by: Joshua Crofts Signed-off-by: Jonathan Cameron List of files: /linux/Documentation/ABI/testing/sysfs-bus-iio

Mon, 27 Jul 2026 23:32:18 +0200

iio: ABI: Encourage differential voltage ABI usageSo far, parts that could only do differential voltage measurements wereonly required to have a consistent labeling of their channels by complyingeither to voltageY or to voltageY-voltageZ ABI. Over time, code maintainerscame to the conclusion that the voltageY-voltageZ ABI is better suited fordifferential-only chips as it provides a simple indication to users thatthe channels measure the difference of two inputs.Adjust the ABI documentation to recommend using the voltageY-voltageZ ABIfor chips that do only differential voltage measurements.Signed-off-by: Marcelo Schmitt Signed-off-by: Jonathan Cameron List of files: /linux/Documentation/ABI/testing/sysfs-bus-iio
