Subject: [PATCH 02/11] Add more flags for sync control
Date: Fri, 19 Nov 2010 13:50:54 +0100 [thread overview]
Message-ID: <1290171063-28870-3-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1290171063-28870-1-git-send-email-jbe@pengutronix.de>
In order to make video mode setup and initializing a runtime job (currently
it is a compile time job) this patch tries to make the 'fb_videomode' structure
more generic. It should also carry special settings required only for some LC
displays. So, I add some additional sync flags to control the DE and CLCK to
the display (something a regular CRT do not know). Also the possibility to
stop the clock when outside active display data (required for (C)STN).
Further suggestions for useful flags?
