[PATCH v7 1/6] iio: ABI: Generalize ABI documentation for DAC

[Kim Seer Paller]

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.

+Contact:	linux-iio@xxxxxxxxxxxxxxx
+Description:
+		Toggle enable. Write 1 to enable toggle or 0 to disable it. This
+		is useful when one wants to change the DAC output codes. For
+		autonomous toggling, the way it should be done is:
+
+		- disable toggle operation;
+		- change out_currentY_rawN, where N is the integer value of the symbol;
+		- enable toggle operation.

+What:		/sys/bus/iio/devices/iio:deviceX/out_currentY_rawN
+KernelVersion:	5.18
+Contact:	linux-iio@xxxxxxxxxxxxxxx
+Description:
+		This attribute has the same meaning as out_currentY_raw. It is
+		specific to toggle enabled channels and refers to the DAC output
+		code in INPUT_N (_rawN), where N is the integer value of the symbol.
+		The same scale and offset as in out_currentY_raw applies.

+What:		/sys/bus/iio/devices/iio:deviceX/out_currentY_symbol
+KernelVersion:	5.18
+Contact:	linux-iio@xxxxxxxxxxxxxxx
+Description:
+		Performs a SW switch to a predefined output symbol. This attribute
+		is specific to toggle enabled channels and allows switching between
+		multiple predefined symbols. Each symbol corresponds to a different
+		output, denoted as out_currentY_rawN, where N is the integer value
+		of the symbol. Writing an integer value N will select out_currentY_rawN.
