2007-04-27V4L/DVB (5306): Add support for VIDIOC_G_CHIP_IDENTHans Verkuil
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>
2007-04-27V4L/DVB (5290): Add support for VIDIOC_INT_G/S_STD_OUTPUTHans Verkuil
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.

2007-03-01V4L/DVB (5304): Improve chip matching in v4l2_registerHans Verkuil
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>
2007-02-21V4L/DVB (5163): Add checks for CAP_SYS_ADMIN to VIDIOC_DBG_G_REGISTERTrent Piepho
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>
2007-02-21V4L/DVB (5146): Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal onlyTrent Piepho
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>

2006-01-05[PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer neededGreg Kroah-Hartman
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.)

2006-01-05[PATCH] i2c: Drop i2c_driver.{owner,name}, 5 of 11Laurent Riffard
We should use the i2c_driver.driver's .name and .owner fields instead of the i2c_driver's ones. This patch updates the drivers/media/video and usb/media drivers.

2006-01-05[PATCH] i2c: Rework client usage count, 2 of 3Jean Delvare
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. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-01-05[PATCH] i2c: Drop i2c_driver.flags, 2 of 3Jean Delvare
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>
