From 065504d5b45bc780b8da221162145a4c9ec67ffc Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 14 Apr 2019 07:59:32 -0300 Subject: docs: lcd-panel-cgram.txt: convert docs to ReST and rename to *.rst This small text file describes the usage of parallel port LCD displays from userspace PoV. So, a good candidate for the admin guide. While this is not part of the admin-guide book, mark it as :orphan:, in order to avoid build warnings.
