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>
2009-03-30v4l2: use old-style i2c API for kernels < 2.6.26 instead of < 2.6.22Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Originally the intention was to switch to the new style i2c API starting with the introduction of the API in 2.6.22. However, the i2c_new_probed_device() function has a lethal bug that wasn't fixed until 2.6.25. Or more accurately, it was only fixed in the stable series of 2.6.25 and 2.6.26. Given the fact that the new i2c API also changed starting with 2.6.26 (the addition of i2c_device_id), it is easiest to switch APIs starting with 2.6.26. This patch updates all the legacy code accordingly. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2009-02-19zoran i2c modules: remove i2c autoprobing support.Hans Verkuil

2009-01-10saa7127: fix broken S-Video with saa7129Hans Verkuil
From: Martin Dauskardt <martin.dauskardt@gmx.de> Register 0x2d has to be set differently in the saa7129 compared to the saa7127. This was not done correctly, so S-Video was broken in certain circumstances. This fixes a regression introduced in 2.6.28.

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.

2008-07-17saa7127: Make device detection optionalHans Verkuil
From: Jean Delvare <khali@linux-fr.org> The saa7127 driver supports all of SAA7126, SAA7127, SAA7128 and SAA1729 devices. Declare all these devices, so that board drivers can tell which device is present, instead of always relying on auto-detection (which needs to write to the chip, eek!). We still need the detection for ivtv, so a special device name "saa7127_auto" can be used when the caller doesn't know exactly which device is present.

This patch allows new-style i2c chip drivers to have alias names using the official kernel aliasing system and MODULE_DEVICE_TABLE().

2007-08-25ivtv: VBI cleanups and fixesHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Besides some VBI cleanups this patch also fixes a subtle problem with the VBI re-insertion stream where the PIO work handler wasn't called quickly enough, resulting in occasional corrupt data. Furthermore the CC output didn't disable CC correctly and at the right time, causing duplicates to be sent. An saa7127 fix for VPS output was also added: the wrong data was sent. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-02-27Improve VIDIOC_G_CHIP_IDENT (better diagnostics)Hans Verkuil
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. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
2007-02-24Add support for VIDIOC_G_CHIP_IDENTHans Verkuil
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. This ioctl replaces the internal VIDIOC_INT_G_CHIP_IDENT ioctl. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> CC: Jonathan Corbet <corbet@lwn.net>
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>
2007-01-30Add checks for CAP_SYS_ADMIN to VIDIOC_DBG_G_REGISTERTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Before, root privileges were only needed to set hardware registers, not to read them. On some hardware, reading from the wrong place at the wrong time can hang the machine. So, to be consistent, root privileges are required to read registers on all hardware. 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>
