Cristian Pop b1a1fd93e1 Documentation/ABI/testing: Add documentation for AD5766 new ABI 
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.

What: /sys/bus/iio/devices/iio:deviceX/in_voltageY_dither_enable KernelVersion: 5.12 Contact: linux-iio@vger.kernel.org Description: Dither enable. Write 1 to enable dither or 0 to disable it.

What: /sys/bus/iio/devices/iio:deviceX/in_voltageY_dither_invert KernelVersion: 5.12 Contact: linux-iio@vger.kernel.org Description: Inverts the dither applied to the selected DAC channel. Dither is not inverted by default. Write "1" to invert dither.

What: /sys/bus/iio/devices/iio:deviceX/in_voltageY_dither_scale_available KernelVersion: 5.12 Contact: linux-iio@vger.kernel.org Description: Returns possible scalings available for the current channel.

What: /sys/bus/iio/devices/iio:deviceX/in_voltageY_dither_scale KernelVersion: 5.12 Contact: linux-iio@vger.kernel.org Description: Scales the dither before it is applied to the selected channel.

What: /sys/bus/iio/devices/iio:deviceX/in_voltageY_dither_source KernelVersion: 5.12 Contact: linux-iio@vger.kernel.org Description: Selects dither source applied to the selected channel. Write "0" to select N0 source, write "1" to select N1 source.
