2018-07-04media: sta2x11: Add video_device and vb2_queue locksEzequiel Garcia
Currently, this driver does not serialize its video4linux ioctls, which is a bug, as race conditions might appear. In addition, video_device and vb2_queue locks are now both mandatory. Add them, and implement wait_prepare and wait_finish. To stay on the safe side, this commit uses a single mutex for both locks. Better latency can be obtained by separating these if needed.

2018-05-28media: Remove depends on HAS_DMA in case of platform dependencyGeert Uytterhoeven
Remove dependencies on HAS_DMA where a Kconfig symbol depends on another symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST". In most cases this other symbol is an architecture or platform specific symbol, or PCI. Generic symbols and drivers without platform dependencies keep their dependencies on HAS_DMA, to prevent compiling subsystems or drivers that cannot work anyway. This simplifies the dependencies, and allows to improve compile-testing. Note: - The various VIDEOBUF*DMA* symbols had to loose their dependencies on HAS_DMA, as they are selected by several individual drivers.

2018-05-09media: sta2x11: Use gpio_is_valid() and remove unnecessary checkArvind Yadav
Replace the manual validity checks for the GPIO with the gpio_is_valid(). In vip_gpio_reserve(), Error checking for gpio pin is not correct. If pwr_pin = -1, It will return 0. This should be return an error. In sta2x11_vip_init_one(), Error checking for gpio 'reset_pin' is unnecessary. Because vip_gpio_reserve() is also checking for valid gpio pin. So removed extra error checking for gpio 'reset_pin'.

2015-12-18[media] vb2: drop v4l2_format argument from queue_setupHans Verkuil
The queue_setup callback has a void pointer that is just for V4L2 and is the pointer to the v4l2_format struct that was passed to VIDIOC_CREATE_BUFS. The idea was that drivers would use the information from that struct to buffers suitable for the requested format. After the vb2 split series this pointer is now a void pointer, which is ugly, and the reality is that all existing drivers will effectively just look at the sizeimage field of v4l2_format. To make this more generic the queue_setup callback is changed: the void pointer is dropped, instead if the *num_planes argument is 0, then use the current format size, if it is non-zero, then it contains the number of requested planes and the sizes array contains the requested sizes. If either is unsupported, then return -EINVAL, otherwise use the requested size(s). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2015-02-02[media] adv7180: Add media controller supportLars-Peter Clausen
Add media controller support to the adv7180 driver by registering a media entity instance for it as well as implementing pad ops for configuring the format. As there currently don't seem to be any users of the video ops format operations those are removed as well in this patch. Also set the V4L2_SUBDEV_FL_HAS_DEVNODE flag for the subdevice so it is possible to create a subdevice device node. Since the driver now depends on VIDEO_V4L2_SUBDEV_API all drivers which select the driver need to depend on that symbol as well.

2014-07-17[media] v4l: Support extending the v4l2_pix_format structureLaurent Pinchart
The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.

2014-04-23[media] vb2: stop_streaming should return voidHans Verkuil
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.

2014-03-11[media] vb2: call buf_finish from __queue_cancelHans Verkuil
If a queue was canceled, then the buf_finish op was never called for the pending buffers. So add this call to queue_cancel. Before calling buf_finish set the buffer state to PREPARED, which is the correct state. That way the states DONE and ERROR will only be seen in buf_finish if streaming is in progress. Since buf_finish can now be called from non-streaming state we need to adapt the handful of drivers that actually need to know this.
