2009-08-10v4l: simplify v4l2_i2c_new_subdev and friendsHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Rewrite v4l2_i2c_new_subdev as a simplified version of v4l2_i2c_new_subdev_cfg and remove v4l2_i2c_new_probed_subdev and v4l2_i2c_new_probed_subdev_addr. This simplifies this API substantially. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

kernel-sync: Author: Alexey Dobriyan <adobriyan@gmail.com> Date: Sat Jul 11 22:08:37 2009 +0400 headers: smp_lock.h redux * Remove smp_lock.h from files which don't need it (including some headers!) * Add smp_lock.h to files which do need it * Make smp_lock.h include conditional in hardirq.h It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT This will make hardirq.h inclusion cheaper for every PREEMPT=n config (which includes allmodconfig/allyesconfig, BTW) Priority: normal Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-04-02v4l2-subdev: change s_routing prototypeHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> It is no longer needed to use a struct pointer as argument, since v4l2_subdev doesn't require that ioctl-like approach anymore. Instead just pass the input, output and config (new!) arguments directly. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2009-04-01v4l2-common: add explicit v4l2_device pointer as first arg to ↵Hans Verkuil
new_(probed)_subdev From: Hans Verkuil <hverkuil@xs4all.nl> The functions v4l2_i2c_new_subdev and v4l2_i2c_new_probed_subdev relied on i2c_get_adapdata to return the v4l2_device. However, this is not always possible on embedded platforms. So modify the API to pass the v4l2_device pointer explicitly. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
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.

2009-03-29cx23885: convert to v4l2_subdev.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Convert this driver to v4l2_subdev. Note that currently the only card with analog support in this driver is the HVR-1800. The analog tuner support in this driver is limited to what is needed for this board. When analog support is added for other cards, then the tuner load code will probably have to be expanded to take care of those boards. For example, there is currently no support for either radio tuners or tda9887 demods. I'd like to thank Steven Toth for testing this on his HVR-1800.

2009-01-09cx23885: Fix Oops for mixed install of analog and digital only cardsAndy Walls
From: Andy Walls <awalls@radix.net> Analog support for HVR-1250 has not been completed, but does exist for the HVR-1800. Since both cards use the same driver, it tries to create the analog dev for both devices, which is not possible. This causes a NULL error to show up in video_open and mpeg_open. -Mark Iterations through the cx23885_devlist must check for NULL pointers as some supported devices only have DVB support at the moment. Mark Jenks encoutered an Oops in a system with both an HVR-1250 and HVR-1800 installed. -Andy Reported-by: Mark Jenks <mjenks1968@gmail.com> Priority: normal Tested-by: Mark Jenks <mjenks1968@gmail.com> Signed-off-by: Mark Jenks <mjenks1968@gmail.com> Signed-off-by: Andy Walls <awalls@radix.net>
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.

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.

2008-10-19v4l: use video_device.num instead of minor in video%dHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now independent of the minor number. So instead of using the minor field of the video_device struct one has to use the num field: this always contains the kernel number of the device node. I forgot about this when I did the v4l2 core change, so this patch converts all drivers that use it in one go. Luckily the change is trivial.

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.

From: Hans Verkuil <hverkuil@xs4all.nl> The functions in a header should not belong to another module. The prio functions belong to v4l2-common.c, so move them to v4l2-common.h. The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header and move those functions to it. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
