When applications modify preview engine parameters, the new values are applied to the hardware by the preview engine interrupt handler during vertical blanking. If the parameters are being changed when the interrupt handler is called, it just delays applying the parameters until the next frame. If an application modifies the parameters for every frame, and the preview engine interrupt is triggerred synchronously, the parameters are never applied to the hardware. Fix this by storing new parameters in a shadow copy, and switch the active parameters with the shadow values atomically. Signed-off-by:

Instead of using a large switch/case statement to return offsets to and sizes of individual preview engine parameters in the parameters and configuration structures, store the information in the update_attrs table and use it at runtime. Signed-off-by:

The preview engine parameters are referenced by a value suitable for being used in a bitmask. Two macros named OMAP3ISP_PREV_* and PREV_* are declared for each parameter and are used interchangeably. Remove the private macro. Replace the configuration bit field in the parameter update attributes structure with a boolean that indicates whether the parameter can be updated through the preview engine configuration ioctl.

If no parameter needs to be modified, make preview_config() and preview_setup_hw() return immediately. This speeds up interrupt handling in the common case. Signed-off-by:

Brightness and contrast are handled through V4L2 controls. Their configuration bit in the preview engine update attributes table is set to -1 to reflect that. However, the VIDIOC_OMAP3ISP_PRV_CFG ioctl handler doesn't handle -1 correctly as a configuration bit value, and erroneously considers that the parameter has been selected for update by the ioctl caller. Fix this. Signed-off-by:

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. Reported-by:

iommu_domain_free() was called in isp_remove() before omap3isp_put(). omap3isp_put() must not save the context if the IOMMU no longer is there. Fix this. Signed-off-by:

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. Fixes: NB#291334 - camera: Recover gracefully from ISP crash instead of oopsing Signed-off-by:

The V4L querystd implementation appears to want to narrow down the list of available standards by starting with a hardware-supported list and then attempting to detect which among those are actually available. Prior to this change in the pvrusb2 driver we started with all possible standards. With this change in place we instead narrow to just the standards that we know the hardware can actually support. For example, this removes the ATSC standards from the list if we aren't dealing with a hybrid device... Signed-off-by:

Get rid of pvrusb2-local implementation for enumeration of video standards - with video_ioctl2 this happens automatically now in the v4l core. Signed-off-by:

With the transition to ioctl2, the pvrusb2 driver's own standards enumeration is no longer used. Instead a generic algorithm internal to v4l is used (which is a great idea - since the pvrusb2 implementation itself was generic anyway). This change ensures that the v4l algorithm works with the correct set of hardware supported standards. This resolves a FIXME left behind from the videodev_ioctl2 transition. Signed-off-by:

Other aspects of the pvrusb2 driver - including in particular those dealing with video standards - all use internal control IDs for uniform access by the interfaces. By exporting the querystd result as another control ID, uniform access to it becomes available through the sysfs interface. Signed-off-by:

Note: there is one FIXME remaining: the tvnorms field of struct video_device should be set up correctly. I have used V4L2_STD_ALL for now, but I'm sure this can be improved. This field is used by video_ioctl2 to implement ENUMSTD. Signed-off-by:

In any statically initialized data structure, the compiler is going to zero any part which is not already explicitly initialized. While we can take that knowledge overboard and simply avoid initializing anything that needs to be zero, it's at least a good idea not to bother zeroing parts that we don't otherwise care about - like "reserved" fields which may change in the future. Avoiding initialization of those fields now also avoids possible conflict down the road. Signed-off-by:

This allows v4l2 control UI-s to update the inactive state (ie grey-ing out of controls) for slave controls when the master control changes. [Use __uvc_find_control() to find slave controls, as they're always located in the same entity as the corresponding master control] Signed-off-by:
