Subject: [PATCH v4 17/28] docs: pcmcia: convert docs to ReST and rename to *.rst
Date:   Wed, 12 Jun 2019 14:52:53 -0300
Message-Id: <d25c0e1c4401d6882507937c7134944ab6c5932c.1560361364.git.mchehab+samsung@kernel.org>

Precedence: bulk

Convert the pcmcia docs to ReST format. Most of the changes here
are trivial.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

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.
