Subject: [PATCH v2 48/79] docs: driver-model: convert docs to ReST and rename to *.rst
Date:   Mon, 22 Apr 2019 10:27:37 -0300
Message-Id: <dbd6b1ffee1bc31c89d0816588f13a7f91bc9f66.1555938376.git.mchehab+samsung@kernel.org>
In-Reply-To: <cover.1555938375.git.mchehab+samsung@kernel.org>
References: <cover.1555938375.git.mchehab+samsung@kernel.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Convert the various documents at the driver-model, preparing
them to be part of the driver-api book.

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.
