[PATCH 0/3] Define and enable camera interface clock

[Werner Almesberger]

This patch series corrects the name of the camera clock, adds the
real camera clock, and explicitly enables it.

We need to do this since Qi turns off many of the clocks it doesn't
use after commit a24b5fcf84d2cf633a3f660edd23fa4c2a3da231

Ben, patches 1/3 and 2/3 are generic and should be of interest for
you.

Andy, this patch series is based on the patch that moves power 
control to he driver. It's not in git yet, so please remember to 
apply it first.

This patch series is only partially tested since that clock gating
change also broke the LCM driver. (Matt is working on it.)
