* | | [media] exynos-gsc: Use user configured colorspace if providedThibault Saunier2017-06-132-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use colorspace provided by the user as we are only doing scaling and color encoding conversion, we won't be able to transform the colorspace itself and the colorspace won't mater in that operation. Also always use output colorspace on the capture side. If the user does not provide a colorspace do not make it up, we might later while processing need to figure out the colorspace, which is possible depending on the frame size but do not ever guess and leak that guess to the userspace.

* | | [media] s5p-jpeg: fix recursive spinlock acquisitionAlexandre Courbot2017-06-131-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | v4l2_m2m_job_finish(), which is called from the interrupt handler with slock acquired, can call the device_run() hook immediately if another context was in the queue. This hook also acquires slock, resulting in a deadlock for this scenario. Fix this by releasing slock right before calling v4l2_m2m_job_finish(). This is safe to do as the state of the hardware cannot change before v4l2_m2m_job_finish() is called anyway.

Fix this by moving the mdp component nodes up a level such that they are siblings of mdp and all other SoC subsystems. This also simplifies the device tree. Although it fixes iommu assignment issue, it also break compatibility with old device tree. So, the patch in driver is needed to iterate over sibling mdp device nodes, not child ones, to keep driver work properly.

Cleanup those assumptions, and also query the subdev for format information and use that if available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Capture driver silently overrides pixel format with a hack (according to the comments) to pass v4l2 compliance tests. This isn't needed for normal functionality, and works for composite video and raw camera capture without. In addition, the hack assumes that it only supports raw capture with a single format (SBGGR8) which isn't true. VPIF can also capture 10- and 12-bit raw formats as well. Forthcoming patches will enable VPIF input with raw-camera support and has been tested with 10-bit format from the aptina,mt9v032 sensor. Any compliance failures should be fixed with a real fix.

* | [media] rcar-vin: allow switch between capturing modes when stallingNiklas Söderlund2017-06-061-5/+17

Once it have been feed one or more free buffers it will recover from the stall and resume capturing. Instead of continue to capture using the same capture mode as before the stall allow the driver to choose between single and continuous mode based on free buffer availability. Do this by stopping capturing when the driver becomes stalled and restart capturing once it continues. By doing this the capture mode will be evaluated each time the driver is recovering from a stall. This behavior is needed to fix a bug where continuous capturing mode is used, userspace is about to stop the stream and is waiting for the last buffers to be returned from the driver and is not queuing any new buffers. In this case the driver becomes stalled when there are only 3 buffers remaining streaming will never resume since the driver is waiting for userspace to feed it more buffers before it can continue streaming. With this fix the driver will then switch to single capture mode for the last 3 buffers and a deadlock is avoided.

* | [media] rcar-vin: move subdev source and sink pad index to rvin_graph_entityNiklas Söderlund2017-06-062-14/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It makes more sense to store the sink and source pads in struct rvin_graph_entity since that contains other subdevice related information. The data type to store pad information in is unsigned int and not int, change this. While we are at it drop the _idx suffix from the names, this never made sense.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rcar-vin driver only uses one pad, pad number 0. - All v4l2 operations that did not check that the requested operation was for pad 0 have been updated with a check to enforce this. - All v4l2 operations that stored (and later restored) the requested pad before substituting it for the subdevice pad number have been updated to not store the incoming pad and simply restore it to 0 after the subdevice operation is complete.

| | | | | | | | | | | | | | | | | | | | | | | | | | As of commit bb475230b8e5 ("reset: make optional functions really optional"), the reset framework API calls use NULL pointers to describe optional, non-present reset controls. This allows to return errors from devm_reset_control_get_optional without special cases and to call reset_control_reset unconditionally.

The pointer used by pcdev_to_dev() is still uninitialized during the call to mclk_get_divisor() as it happens in v4l2_device_register() at the end of the probe. The dev_warn and dev_dbg caused a line in the log: (NULL device *): Limiting master clock to 26000000 Fix this by using an initialized pointer from the platform_device (as before the old patch).
