Hi, All
	the following is the patch set that adds the default modes for LVDS in KMS
mode.
	Patch 1/3: Add a private data for LVDS
		When the connector type is LVDS, it will add a private data that 
can be used to store the LVDS panel limit. For example: hdisplay, vdisplay.
	
	Patch 2/3: Get the LVDS panel limit and check whether the given modeline
is valid
		Traverse the mode list returned by KMS kernel to get the LVDS panel
limit. And the panel limit is used to check whether the given modeline is valid.

	Patch 3/3: Add the default modes for the LVDS
		

welcome the comments.

Best regards
