Mauro/Russell, The previous version (v2) of this patch is on the linux-next tree. This patch has some updates done on top of that patch. Should I post an incremental patch for those changes to the Linux-next tree? Please suggest.

Mauro, OK. Thank you for taking care of this.

Chaithrika, Could you send the patches inline to Russell King rmk@arm.linux.org.uk? This was what Mauro had suggested to me. We need to get a resolution on this quickly since I have some patches waiting to be submitted against display driver and would like to base it on your patches.
