2008-08-09v4l2: add AAC bitrate controlHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> If you can select AAC as audio encoder, then you should also be able to set the bitrate. Add this missing control. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-08-08saa6752hs: cleanup and add AC-3 supportHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Cleaned up the saa6752hs i2c driver. Add AC-3 support. Add VIDIOC_CHIP_IDENT support. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-08-08v4l2: add v4l2_ctrl_query_menu_valid_items support functionHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> v4l2_ctrl_query_menu_valid_items() makes it easy to handle control menus that have a lot of invalid 'holes'. For example, many MPEG encoders only support a limited subset of audio bitrates. In that case a driver can specify an array listing the set of valid bitrates and pass that to this function. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2008-08-08v4l2: add v4l2_ctrl_get_name control support function.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Add function that returns the control name. Allows this to be used in places where the normal v4l2_ctrl_query_fill() function cannot be used (e.g. uvc). Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

From: Mauro Carvalho Chehab <mchehab@infradead.org> kernel-sync: Author: Jean Delvare <khali@linux-fr.org> Date: Tue Apr 29 23:11:39 2008 +0200 i2c: Add support for device alias names Based on earlier work by Jon Smirl and Jochen Friedrich. This patch allows new-style i2c chip drivers to have alias names using the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this point, the old i2c driver binding scheme (driver_name/type) is still supported. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-02-02Fix Kconfig dependenciesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes. This patch moves the functions that videodev needs from v4l2-common. It also fixes some Kconfig changes. After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked into kernel. v4l2-common will be m, and all V4L drivers will also be m. This approach is very conservative, since it is possible to have V4L drivers that don't need I2C or v4l2-common. The better is to map what drivers really need v4l2-common, making them to select v4l2-common, and allowing the others to be 'y', 'm' and 'n'.

2007-09-12v4l2: add support for bus-based I2C driversHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Two new headers were added: one for I2C drivers that are only used by V4L2 drivers converted to the new bus-based I2C API, and one that can be used by both converted and unconverted drivers (at the expense of some additional overhead). To support the legacy I2C API a helper function was added to v4l2-common.c. These headers take care of all the 'boilerplate' code that all V4L2 I2C drivers have in common and will automatically support the bus-based I2C API introduced in kernel 2.6.22.

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>

2007-08-21cx2341x: some controls should not be changed while the device is busy.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The driver should now pass the 'busy' state of the device to the cx2341x module whenever controls are set or tried. -EBUSY will be returned if the device is busy and the user attempts to modify certain 'dangerous' controls. It concerns controls that change the audio or video compression mode and bitrates. The cx88-blackbird and pvrusb2 drivers currently always pass '0' (not busy) to the cx2341x, effectively keeping the old behavior for now. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

From: Hans Verkuil <hverkuil@xs4all.nl> If v4l2_ctrl_next is called without the V4L2_CTRL_FLAG_NEXT_CTRL then it should check whether the passed control ID is valid and return 0 if it isn't. Otherwise a for-loop over the control IDs will never end. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

From: Hans Verkuil <hverkuil@xs4all.nl> Simplify the VIDIOC_G_CHIP_IDENT implementation by adding a single common function. The ident can now also return NONE: not found, UNKNOWN: found, but we don't know what chip it is, and AMBIGUOUS: multiple chips were matched so the match values were too general.

From: Hans Verkuil <hverkuil@xs4all.nl> VIDIOC_G_CHIP_IDENT improves debugging of card problems: it can be used to detect which chips are on the board and based on that information selected register dumps can be made, making it easy to debug complicated media chips containing tens or hundreds of registers.

2007-02-24Improve chip matching in v4l2_register for VIDIOC_DBG_G/S_REGISTERHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The chip matching in struct v4l2_register was rather primitive. It could not be extended to other busses besides i2c and it lacked a way to differentiate between two i2c chips driven by the same driver on one board (e.g. a PVR500 with two tuner chips, one for analog TV and one for radio). It has now been improved making it much more powerful. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> CC: Mike Isely <isely@isely.net> CC: Trent Piepho <xyzzy@speakeasy.org>
2007-02-21Add support for VIDIOC_INT_G/S_STD_OUTPUTHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Added VIDIOC_INT_G_STD_OUTPUT and VIDIOC_INT_S_STD_OUTPUT to allow drivers to set the TV standard for video output separately from the video capture. This is needed for cx23415 support where the decoder is separate from the encoder and can have a different TV standard. Modified the saa7127 module to listen to VIDIOC_INT_G/S_STD_OUTPUT instead of VIDIOC_G/S_STD. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-02-19compat: Add -include linux/version.h to cflagsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Add -include linux/version.h to the cflags. Now code can have backward compatibility test without including compat.h first. Linux headers included from compat.h are removed, so that code will get the same headers when compiling in v4l-dvb as it does in the kernel. Many drivers have compat.h moved to the end of their include list, as this lets compat.h do things it can't do at the beginning. Such as test of something is defined to include compat code, or to put a wrapper around a function without changing the function's name. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

2007-01-23Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal onlyTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The direct register access ioctls were defined as kernel internal only, but they are very useful for debugging hardware from userspace and are used as such. Officially export them. VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER Definition of ioctl and struct v4l2_register is moved from v4l2-common.h to videodev2.h. Types used in struct v4l2_register are changed to the userspace exportable versions (u32 -> __u32, etc). Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move the check into the video_ioctl2() dispatcher so it doesn't need to be duplicated in each driver's call-back function. CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2). Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

2006-11-20Remove the need of a STD array for drivers using video_ioctl2Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> CC: Jonathan Corbet <corbet@lwn.net> video_ioctl2 will auto-generate standard entries at ENUM_FMT. Also, now, a driver may return a subset of the video array at the return, to be stored as the current_norm. For example, a driver may ask for V4L2_STD_PAL. At return, driver may change it to V4L2_STD_PAL_B. This way, a futher call to G_STD will return the exact detected video std. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
