Julien Stephan 0e1168f8f2 iio: adc: ad7380: fix oversampling formula
The formula in the datasheet for oversampling time conversion seems to
be valid when device is at full speed using the maximum number of SDO
lines. The driver currently support only 1 SDO line. The correct formula
is: t_convert = T_CONVERT_0_NS + T_CONVERT_X_NS*(x -
1)*num_channel/number_of_sdo_lines.
It will produce larger delays than what is currently set, but some devices
actually require it.

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.
