When a fatal error that prevents any further video streaming occurs in a pipeline, all queued buffers must be marked as erroneous and new buffers must be prevented from being queued.

The clock core code is going to be modified so clk_get() takes reference on the clock provider module. Until the potential circular reference issue is properly addressed, we pass NULL as the first argument to clk_register(), in order to disallow sub-devices taking a reference on the ISP module back trough clk_get().

Currently the media device link_notify callback is invoked before the actual change of state of a link when the link is being enabled, and after the actual change of state when the link is being disabled. This doesn't allow a media device driver to perform any operations on a full graph before a link is disabled, as well as performing any tasks on a modified graph right after a link's state is changed. This patch modifies signature of the link_notify callback. This callback is now called always before and after a link's state change. To distinguish the notifications a 'notification' argument is added to the link_notify callback: MEDIA_DEV_NOTIFY_PRE_LINK_CH indicates notification before link's state change and MEDIA_DEV_NOTIFY_POST_LINK_CH corresponds to a notification after link flags change.

Looks like the iommu framework does not have generic functions exported for all the needs yet. The hardware specific functions are defined in files like intel-iommu.h and amd-iommu.h. Follow the same standard for omap-iommu.h. This is needed because we are removing plat and mach includes for ARM common zImage support. Further work should continue in the iommu framework context as only pure platform data will be communicated from arch/arm/*omap*/* code to the iommu framework.

When propagating the frame number through the pipeline, the frame number must be incremented at frame start by the appropriate IRQ handler. This was properly handled for the CSI2 and CCP2 receivers, but not when the CCDC parallel interface is used. ADD frame number incrementation to the HS/VS interrupt handler. As the HS/VS interrupt is also generated for frames received by the CSI2 and CCP2 receivers, remove explicit propagation handling from the serial receivers.

The OMAP3 ISP preview engine will violate the L4 bus protocol if we try to write some of its internal registers after it failed to stop properly. This generates an external abort on non-linefetch fault, triggering a fatal kernel oops. We can't always prevent preview engine stop failures (they can for instance be caused by a sensor crash), but we can improve the system reliability by refusing to start streaming on a pipeline that contains the preview engine if it failed to stop. The driver will then eventually reset the ISP (when all applications will have closed their file handles related to OMAP3 ISP device nodes), making the ISP usable again.
