2009-05-08saa7134-video.c: fix the block bugMauro Carvalho Chehab
From: figo.zhang <figo.zhang@kolorific.com> when re-open or re-start (video_streamon), the q->curr would not be NULL in saa7134_buffer_queue(), and all the qbuf will add to q->queue list,no one to do activate to start DMA,and then no interrupt would happened,so it will be block. In VIDEOBUF_NEEDS_INIT state, initialize the curr pointer to be NULL in the buffer_prepare().

2009-04-01v4l2-subdev: move s_std from tuner to core.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> s_std didn't belong in the tuner ops. Stricly speaking it should be part of the video ops, but it is used by audio and tuner devices as well, so it is more efficient to make it part of the core ops.

2009-02-09saa7134: get rid of KBLMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@redhat.com> KBL is not needed on saa7134, so, let's remove it. However, we should take some care to avoid opening the module while initializing it. This issue exists with newer udev's that opens a device as soon as the driver is registered. So, a proper lock is needed on open. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-12-30v4l2: debugging API changed to match against driver name instead of ID.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Since the i2c driver ID will be removed in the near future we have to modify the v4l2 debugging API to use the driver name instead of driver ID. Note that this API is not used in applications other than v4l2-dbg.cpp as it is for debugging and testing only. Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged with a warning that it is deprecated and will be removed in 2.6.30. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-12-30v4l2: introduce v4l2_file_operations.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-10-03v4l: remove vidioc_enum_fmt_vbi_capHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Remove the vidioc_enum_fmt_vbi_cap ops: it was scheduled for removal in 2.6.28 since the v4l2 specification says that V4L2_BUF_TYPE_VBI_CAPTURE should not support VIDIOC_ENUM_FMT. It's also pretty pointless. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-09-06saa7134-empress: fix changing the capture standard for non-tuner inputsHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> When changing the standard the saa6752hs was not updated unless the input was the TV tuner. The saa6752hs should be updated regardless of the input. In addition the S_STD and G_STD ioctls for the mpeg video device didn't do anything. This is now fixed: they behave just like S_STD and G_STD on the video0 device. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-07-30v4l: move BKL down to the driver level.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The BKL is now moved from the video_open function in v4l2-dev.c to the various drivers. It seems about a third of the drivers already has a lock of some sort protecting the open(), another third uses video_exclusive_open (yuck!) and the last third required adding the BKL in their open function.

2008-07-26v4l2-dev: remove unused type and type2 field from video_deviceHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The type and type2 fields were unused and so could be removed. Instead add a vfl_type field that contains the type of the video device. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-07-21videodev: move all ioctl callbacks to a new v4l2_ioctl_ops structHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it. This ensures a clean separation between the const ops struct and the non-const video_device struct.

2007-10-18Replace TDA9887_SET_CONFIG by TUNER_SET_CONFIGMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Currently, the only tuner-specific device that allows special configurations is tda9887. However, tea5767 also may require some special configurations (for example, to specify a different Xtal freq). This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl (TUNER_SET_CONFIG). The newer one allows specifying what tuner is appliable to a configuration set, and allows an arbitrary configuration struct. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-12 Additional Fixes for saa7134 suspend/resumeMauro Carvalho Chehab
From: Maxim Levitsky <maximlevitsky@gmail.com> Fixes few more problems I found in my saa7134 resume code: * Race between IRQ handler and .suspend()/.resume() functions * Removes timeout timers on active buffers - those buffers will be recaptured after resume * Adds suspend/resume for IR code - probably necessary if using polling mode * Adds #ifdef CONFIG_PM overs suspend code * Runs a quirk in set_tvnorm in suspend/resume too * Rearranges the order of calls in saa7134_resume to be exactly as in saa7134_initdev thus the card is initialized in exactly the same way * Since DMA audio capture suspend/resume isn't yet supported, avoid re-enabling it on resume for now Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-15v4l core: remove the unused .hardware V4L1 fieldMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> struct video_device used to define a .hardware field. While initialized on severl drivers, this field is never used inside V4L. However, drivers using it need to include the old V4L1 header. This seems to cause compilation troubles with some random configs. Better just to remove it from all drivers.
