Subject: [PATCH 1/4] drm/dsi: Add flag for continuous clock behavior
Date: Wed,  2 Jul 2014 21:19:17 +0900	[thread overview]
Message-ID: <1404303560-32209-2-git-send-email-acourbot@nvidia.com> (raw)
In-Reply-To: <1404303560-32209-1-git-send-email-acourbot@nvidia.com>

As per section 5.6.1 of the DSI specification, all DSI transmitters must
support continuous clock behavior on the clock lane, while non-continuous
mode support is only optional. Add a flag that allows devices to indicate
that they require continuous clock mode to operate properly.
