My primary object is to put base patch in Linux. once it done other things can be enabled one by one.

Any features which are not enabled must be specified in the patch 
description.  The patch says that the board supports DIU, but the code 
doesn't, so that's misleading.

Also, I am not familiar with DIU driver:(.

I can help you with the DIU driver.

shall I remove the DIU node, and  while adding support of DIU, all modification will be sent.

I think it should be okay to leave the DIU node.  I think the kernel 
will crash if you try to enable a DIU console (video= on the kernel 
command line), but I think it's okay to ignore that for the moment.

Sounds like a bug in the DIU driver.  It should fail gracefully in the
absence of platform support.
