omap4iss driver code missing in Linaro 12.07

Hi,

I have the source code of Linaro ICS kernel 3.4 (Linaro version 12.07). In this kernel source code V4L2 driver related to omap4 Camera (omap4 iss) is missing. In the earlier ICS kernel 3.2, it was under the folder drivers/media/video/omap4iss

Is it replaced with some other driver or should I take it from to previous ICS kernel 3.2 version?

Please provide some pointers related to this.
