* V4L/DVB (8379): saa7127: Make device detection optionalJean Delvare2008-07-20
| | | | | | | | | | | | | | | 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.

* v4l-dvb: remove legacy checks to allow support for kernels < 2.6.10Hans Verkuil2008-07-20
| | | | | | | | Also remove some blank lines that were used to split compat code at -devel tree. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* i2c: Convert remaining new-style drivers to use module aliasingJean Delvare2008-05-18
| | | | | | | | | | | | Update all the remaining new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. Note that the tuner driver is a bit quirky at the moment, as it overwrites i2c_client.name with arbitrary strings. We write "tuner" back on remove, to make sure that driver cycling will work properly, but there may still be troublesome corner cases. Signed-off-by: Jean Delvare <khali@linux-fr.org>
* i2c: Add support for device alias namesJean Delvare2008-04-29
| | | | | | | | | | | | | | 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.

* V4L/DVB (6465): Use correct error codes when chip is not recognizedHans Verkuil2008-01-25
| | | | | | | | | | If the chip isn't recognized, then the correct errors should be returned. The v4l2_i2c_attach() utility function will return 0 for all errors except -ENOMEM to provide proper compatibility support for the old I2C probing function.

* V4L/DVB (6116): ivtv: VBI cleanups and fixesHans Verkuil2007-10-09
| | | | | | | | | | | | | | 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.

* V4L/DVB (5306): Add support for VIDIOC_G_CHIP_IDENTHans Verkuil2007-04-27
| | | | | | | | | | | 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> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (5290): Add support for VIDIOC_INT_G/S_STD_OUTPUTHans Verkuil2007-04-27
| | | | | | | | | | | | 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.

* V4L/DVB (5304): Improve chip matching in v4l2_registerHans Verkuil2007-03-01
| | | | | | | | | The chip matching in struct v4l2_register for VIDIOC_DBG_G/S_REGISTER was rather primitive. It could not be extended to other busses besides i2c and it lacked a way to. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (5163): Add checks for CAP_SYS_ADMIN to VIDIOC_DBG_G_REGISTERTrent Piepho2007-02-21
| | | | | | | | | | 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> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (5146): Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal onlyTrent Piepho2007-02-21
| | | | | | | | | | | | | | | | | | | | | 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> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* [PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer neededGreg Kroah-Hartman2006-01-06
| | | | | | | | | | Now that i2c_add_driver() doesn't need the module owner to be set by hand, we can delete it from the drivers. This patch catches all of the drivers that I found in the current tree (if a driver sets the .owner by hand, it's not a problem, just not needed.)

* [PATCH] i2c: Rework client usage count, 2 of 3Jean Delvare2006-01-06
| | | | | | | | | Make I2C_CLIENT_ALLOW_USE the default for all i2c clients. It doesn't hurt if the usage count is actually never used for any given driver, and allows for nice code simplifications in i2c-core.

* [PATCH] i2c: Drop i2c_driver.flags, 2 of 3Jean Delvare2006-01-06
| | | | | | | | | | | Just about every i2c chip driver sets the I2C_DF_NOTIFY flag, so we can simply make it the default and drop the flag. If any driver really doesn't want to be notified when i2c adapters are added, that driver can simply omit to set .attach_adapter. This approach is also more robust as it prevents accidental NULL pointer dereferences. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
