Kim Seer Paller 5fe8da6127 iio: ABI: Generalize ABI documentation for DAC 
Introduces a more generalized ABI documentation for DAC. Instead of
having separate ABI files for each DAC, we now have a single ABI file
that covers the common sysfs interface for all DAC.

What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_en KernelVersion: 5.18 Contact: linux-iio@vger.kernel.org Description: Dither enable. Write 1 to enable dither or 0 to disable it. This is useful for changing the dither parameters. They way it should be done is:

	- disable dither operation;
	- change dither parameters (eg: frequency, phase...);
	- enabled dither operation

What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_raw KernelVersion: 5.18 Contact: linux-iio@vger.kernel.org Description: This raw, unscaled value refers to the dither signal amplitude. The same scale as in out_voltageY_raw applies. However, the offset might be different as it's always 0 for this attribute.

What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_raw_available KernelVersion: 5.18 Contact: linux-iio@vger.kernel.org Description: Available range for dither raw amplitude values.

What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_offset KernelVersion: 5.18 Contact: linux-iio@vger.kernel.org Description: Offset applied to out_voltageY_dither_raw. Read only attribute always set to 0.

What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_frequency KernelVersion: 5.18 Contact: linux-iio@vger.kernel.org Description: Sets the dither signal frequency. Units are in Hz.

What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_frequency_available KernelVersion: 5.18 Contact: linux-iio@vger.kernel.org Description: Returns the available values for the dither frequency.

What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_phase KernelVersion: 5.18 Contact: linux-iio@vger.kernel.org Description: Sets the dither signal phase. Units are in Radians.

What: /sys/bus/iio/devices/iio:deviceX/out_voltageY_dither_phase_available KernelVersion: 5.18 Contact: linux-iio@vger.kernel.org Description: Returns the available values for the dither phase.
