IPU2 for CSI parallel camera

I am working on Nitrogen Sabrelite board with extended h/w for enabling dual parallel camera using CSI interface. One camera is working with IPU1-CSI0 combintaion but i am unable to get the second camera up using IPU2-CSI1 parallel interface. I am using current Linux kernel 3.0.35 with release number as 3.0.35_1.1.3. I assume that IPU is initialized properly and we should be able to capture frames atleast.


I have enabled the second camera using board_init functions, required PinMuxes and also additional GPR register setting to enable IPU2-CSI1 connectivity.

mxc_iomux_set_gpr_register(1, 20, 1, 1);


Please guide if there are still things missing from my side.
