That's right. The OMAP3 ISP driver indirectly depended on the iommu2 module, which wasn't loaded automatically. Nowadays OMAP IOMMU support is a boolean option, so it will get compiled in the kernel directly. -- Regards, Laurent Pinchart ^ permalink raw reply [flat|nested] 5+ messages in thread

You should take the latest mainline code and add ISP board code for your board. You can find examples of such board code at http://git.linuxtv.org/pinchartl/media.git/shortlog/refs/heads/omap3isp- sensors-board for the Beagleboard, the Gumstix Overo and the OMAP3 EVM. -- Regards, Laurent Pinchart ^ permalink raw reply [flat|nested] 5+ messages in thread
