linux-iio, lkml
Subsystem:
iio subsystem and drivers, the rest · Maintainers:
Jonathan Cameron, Linus Torvalds
New interface is proposed for dither functionality. This future allows
composing an external signals to the selected output channel.
The dither signal can be turned on/off, scaled, inverted, or it can be
selected from different sources.
Signed-off-by: Cristian Pop <redacted>

Changelog v5:
- Rename property to: "in_voltageY_dither_enable"
- Change scale values to: "1 0.75 0.5 0.25"
- Specify KernelVersion
