The current driver supports only parts with 2 channels.
In order to prepare the support of new compatible ADCs with more
channels, this commit:
- defines MAX_NUM_CHANNEL to specify the maximum number of
channels currently supported by the driver
- adds available_scan_mask member in ad7380_chip_info structure
- fixes spi xfer struct len depending on number of channels
- fixes scan_data.raw buffer size to handle more channels
- adds a timing specifications structure in ad7380_chip_info structure

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 reStructuredText 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.
