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.

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

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.
