Nuno Sá 52302f87d0 iio: ABI: add ABI file for the LTC2688 DAC
Define the sysfs interface for toggle or dither capable channels. Dither
capable channels will have the extended interface:

 * out_voltageY_dither_en
 * out_voltageY_dither_raw
 * out_voltageY_dither_offset
 * out_voltageY_dither_raw_available
 * out_voltageY_dither_frequency
 * out_voltageY_dither_frequency_available
 * out_voltageY_dither_phase
 * out_voltageY_dither_phase_available

Toggle enabled channels will have:

 * out_voltageY_toggle_en
 * out_voltageY_raw0
 * out_voltageY_raw1
 * out_voltageY_symbol

The common interface present in all channels is:

 * out_voltageY_raw (not present in toggle enabled channels)
 * out_voltageY_raw_available
 * out_voltageY_powerdown
 * out_voltageY_scale
 * out_voltageY_offset
 * out_voltageY_calibbias
 * out_voltageY_calibscale

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
