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:

Properly validate the user-supplied index against the number of inputs. The code used the pin local variable instead of the index by mistake. Reported-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:

Note the unused in this patch slave_ids addition to the mappings will get used in a follow up patch to generate control change events for the slave ctrls when their flags change due to the master control changing value. Signed-off-by:

This avoids the need for doing a forward declaration of __uvc_ctrl_get (which is a static function) in later patches in this series. Note to reviewers this patch does not change a single line of code, it just moves the function up in uvc_ctrl.c a bit. Signed-off-by:

Just like with ctrl events, drivers may want to get called back on listener add / remove for other event types too. Rather then special casing all of this in subscribe / unsubscribe event it is better to use ops for this. Signed-off-by:

This driver was severely broken. This patch makes it work again, and updates it to the latest V4L2 frameworks (except for videobuf2). It passes the v4l2-compliance tests and it now handles suspend/resume correctly. Several custom controls are replaced by new standard controls, only the USB_ALTERNATE control remains. Tested with the Hanse HVS-CM500PC USB microscope. Signed-off-by:

It turns out that the flush to sensor command needs to be done per register bank. We were missing one such flush in set_exposure, causing exposure changes to only show up when another setting in the same bank also got changed. Signed-off-by:

The pac7302 and pac7311 driver still contains some comments from before they were separated, such as marking certain functions 7302 or 7311 only, with the new split drivers these make no sense, remove them. Also removed the empty/unused sd_stop0 function from pac7311.c Signed-off-by:
