* [media] uvcvideo: Fix reading the current exposure value of UVCAnton V. Shokurov2015-12-181-1/+2
| | | | | | | | | | | | V4L2_CID_EXPOSURE_ABSOLUTE property does not return an updated value when autoexposure (V4L2_CID_EXPOSURE_AUTO) is turned on. This patch fixes this issue by adding the UVC_CTRL_FLAG_AUTO_UPDATE flag. Tested on a C920 camera. Signed-off-by: Anton V.

* [media] cx23885-dvb: move initialization of a8293_pdataMauro Carvalho Chehab2015-12-181-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | Smatch complains about where the au8293_data is placed: drivers/media/pci/cx23885/cx23885-dvb.c:2174 dvb_register() info: 'a8293_pdata' is not actually initialized (unreached code). It is not actually expected to have such initialization at switch { foo = bar; case: ... } Not really sure how gcc does that, but this is something that I would expect that different compilers would do different things. David Howells checked with the compiler people: it's not really expected to initialise as expected. So, move the initialization outside the switch(), making smatch to shut up one warning.

* [media] videobuf2-core: fix plane_sizes handling in VIDIOC_CREATE_BUFSHans Verkuil2015-12-181-18/+21
| | | | | | | | | | | | | | | | | | | | The handling of q->plane_sizes was wrong in vb2_core_create_bufs(). The q->plane_sizes array was global and it was overwritten by create_bufs. So if reqbufs was called with e.g. size 100000 then q->plane_sizes[0] would be set to 100000. If create_bufs was called afterwards with size 200000, then q->plane_sizes[0] would be overwritten with the new value. Calling create_bufs again for size 100000 would cause an error since 100000 is now less than q->plane_sizes[0]. This patch fixes this problem by 1) removing q->plane_sizes and using the vb->planes[].length field instead, and 2) by introducing a min_length field in struct vb2_plane. This field is set to the plane size as returned by the queue_setup op and is the minimum required plane size. So user pointers or dmabufs should all be at least this size.

* [media] vb2: drop v4l2_format argument from queue_setupHans Verkuil2015-12-1875-488/+321
| | | | | | | | | | | | | | | | | | | | | 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>

And that's besides the fact that that code is plain wrong. After this change the cx23888 behaves much better.

Add cropcap support. 3) cx23885_set_tvnorm() should just return 0 if the same standard was set again. If another standard is set, then reset the width/height and call set_fmt for the subdevs. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | pci_set_dma_mask returns a negative errno value, not a bool like pci_dma_supported. This of course was just a giant test for attention :) Signed-off-by: Christoph Hellwig <hch@lst.de> Reported-by: Jongman Heo <jongman.heo@samsung.com> Tested-by: Jongman Heo <jongman.heo@samsung.com> [pcnet32] Acked-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com> Cc: Hans Verkuil <hverkuil@xs4all.nl> Cc: Antti Palosaari <crope@iki.fi> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | [media] davinci: add i2c Kconfig dependenciesArnd Bergmann2015-11-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All the davinci media drivers are using the i2c framework, and fail to build if that is ever disabled, e.g.: media/platform/davinci/vpif_display.c: In function 'vpif_probe': media/platform/davinci/vpif_display.c:1298:14: error: implicit declaration of function 'i2c_get_adapter' [-Werror=implicit-function-declaration] This adds explicit Kconfig dependencies so we don't see the driver options if I2C is turned off.
