Subject: [PATCH v1 24/31] docs: iio: convert to ReST
Date: Wed, 12 Jun 2019 15:38:27 -0300
Message-ID: <6b9df01697dde8b9bb9be9accf28d63ed821956d.1560364494.git.mchehab+samsung@kernel.org> (raw)
In-Reply-To: <cover.1560364493.git.mchehab+samsung@kernel.org>

Rename the iio documentation files to ReST, add an
index for them and adjust in order to produce a nice html
output via the Sphinx build system.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.
