Subject: [PATCH v2 53/79] docs: nvmem: convert docs to ReST and rename to *.rst
Date: Mon, 22 Apr 2019 10:27:42 -0300 [thread overview]
Message-ID: <41fe02b98daae3feee8df656e09e0f3c82e201c5.1555938376.git.mchehab+samsung@kernel.org> (raw)
In-Reply-To: <cover.1555938375.git.mchehab+samsung@kernel.org>
In order to be able to add it into a doc book, we need first
convert it to ReST.
The conversion is actually:
- add blank lines and identation in order to identify paragraphs;
- mark literal blocks;
- adjust title markups.
While this is not part of any book, mark it as :orphan:, in order
to avoid build warnings.
