* [media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_configHans Verkuil2015-03-2310-106/+106
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a subdevice pad op is called from a bridge driver, then there is no v4l2_subdev_fh struct that can be passed to the subdevice. This made it hard to use such subdevs from a bridge driver. This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config pointer in the pad ops. This allows bridge drivers to use the various try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it along to the pad op. The v4l2_subdev_get_try_* macros had to be changed because of this, so I also took the opportunity to use the full name of the v4l2_subdev_get_try_* functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do 'git grep v4l2_subdev_get_try_format' you will actually find the header where it is defined. One remark regarding the drivers/staging/media/davinci_vpfe patches: the *_init_formats() functions assumed that fh could be NULL. However, that's not true for this driver, it's always set. This is almost certainly a copy and paste from the omap3isp driver. I've updated the code to reflect the fact that fh is never NULL.

The driver doesn't ensure this correctly as it never clears the mappings. An RPF used with one WPF and later with a different WPF will lead to malfunction, as it will be associated with two WPFs.

* [media] v4l: vsp1: Setup control handler automatically at stream on timeLaurent Pinchart2014-07-172-0/+46
| | | | | | | | | | | | | | | | | | | When setting a control directly on a subdev node the VSP1 driver doesn't guarantee that the device is powered on. This leads to crashes when the control handlers writes to hardware registers. One easy way to fix this is to ensure that the device gets powered on when a subdev node is opened. However, this consumes power unnecessarily, as there's no need to power the device on when setting formats on the pipeline. Furthermore, control handler setup at entity init time suffers from the same problem as the device isn't powered on easier. Fix this by extend the entity base object to setup the control handler automatically when starting the stream. Entities must then skip writing to registers in the set control handler when not streaming, which can be tested with the new vsp1_entity_is_streaming() helper function.

* [media] v4l: vsp1: Cleanup video nodes at removal timeLaurent Pinchart2014-07-174-12/+18
| | | | | | | | | | | | | Video nodes created and initialized in the RPF and WPF init code paths are never unregistered, and the related resources (videobuf alloc context and media entity) never released. Fix this by storing a pointer to the vsp1_video object in vsp1_entity and calling vsp1_video_cleanup() from vsp1_entity_destroy(). This also allows simplifying the init error code paths.

* [media] v4l: vsp1: Fix pipeline stop timeoutLaurent Pinchart2014-07-171-3/+7
| | | | | | | | | | | | | If the pipeline was already stopped when stopping the stream, no frame end interrupt will be generated and the driver will time out waiting for the pipeline to stop. Fix this by setting the pipeline state to STOPPED when the pipeline is idle waiting for frames to process, and to STOPPING at stream stop time only when the pipeline is currently RUNNING.

* [media] v4l: vsp1: Release buffers at stream stopLaurent Pinchart2014-07-171-0/+3
| | | | | | | | | | | | videobuf2 expects no buffer to be owned by the driver when the stop_stream queue operation returns. As the vsp1 driver fails to do so, a warning is generated at stream top time. Fix this by releasing all buffers queued on the IRQ queue in the stop_stream operation handler and marking them as erroneous.

* [media] v4l: vsp1: Fix routing cleanup when stopping the streamLaurent Pinchart2014-07-171-1/+1
| | | | | | | | | | | | | | | Commit d9b45ed3d8b75e8cf38c8cd1563c29217eecba27 ("v4l: vsp1: Support multi-input entities") reworked pipeline routing configuration and introduced a bug by writing to the entities routing registers without first checking whether the entity had a routing register. This results in overwriting the value at offset 0 of the device register space when stopping the stream. Fix this by skipping routing register write for entities without a routing register.

| | | | | | | | | | Scaling of the alpha layer is disabled as both the RPF and WPF are configured to hardcode the alpha value to 255. This results in a 0 alpha value at the UDS output, making the image invisible when alpha blended in the BRU. Fix it by enabling scaling of the alpha layer.

* [media] vb2: stop_streaming should return voidHans Verkuil2014-04-231-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | The vb2 core ignores any return code from the stop_streaming op. And there really isn't anything it can do anyway in case of an error. So change the return type to void and update any drivers that implement it. The int return gave drivers the idea that this operation could actually fail, but that's really not the case. The pwc amd sdr-msi3101 drivers both had this construction: if (mutex_lock_interruptible(&s->v4l2_lock)) return -ERESTARTSYS; This has been updated to just call mutex_lock(). The stop_streaming op expects this to really stop streaming and I very much doubt this will work reliably if stop_streaming just returns without really stopping the DMA.
