From 7c6a2d229dd6dab7cc7563f72b78dd5867d351b4 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Wed, 17 May 2017 10:29:58 -0300 Subject: debugging-via-ohci1394.txt: standardize document format Each text file under Documentation follows a different format. Some doesn't even have titles! Change its representation to follow the adopted standard, using ReST markups for it to be parseable by Sphinx: - Mark and adjust titles; - Mark and indent literal blocks.
