This patch is a prerequisite for a set of 4 patches that need to go through 
the linux-media tree. It would simpler if it could go through the same tree as 
well. Given that arch/arm/mach-omap2/board-cm-t35.c has seen very little 
activity recently I believe the risk of conflict is pretty low. Tony, would 
that be fine with you ?
