2009-01-29V4L/DVB (10314): cx25840: ignore TUNER_SET_CONFIG in the command callback.Hans Verkuil
These days TUNER_SET_CONFIG is broadcast to the other i2c devices and that triggers a fw load on the cx25840. Ignore this command since cx25840 isn't a tuner and you really do not want to load the firmware that early.

2009-01-29V4L/DVB (10250): cx25840: fix regression: fw not loaded on first useHans Verkuil
With the conversion to v4l2_subdev one bit of code was accidentally dropped: on receiving the first command the driver has to load the fw. A new init() command was introduced to do that explicitly for bridge drivers that are converted to use v4l2_subdev, but old drivers that are not yet converted no longer worked. This patch fixes this regression for these old drivers. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-01-02V4L/DVB (10141): v4l2: debugging API changed to match against driver name ↵Hans Verkuil
instead of ID. 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.

2008-10-13V4L/DVB (9162): ivtv: fix raw/sliced VBI mixupHans Verkuil
The service_set field was used in saa7115 and cx25840 to determine whether raw or sliced VBI was desired. This is incorrect since it is perfectly valid to select sliced VBI with a service_set of 0. Instead these drivers should checked on VIDIOC_S_FMT whether the type field matches the raw or sliced VBI type. Updated ivtv accordingly.

2008-05-18i2c: Convert remaining new-style drivers to use module aliasingJean Delvare
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>
2008-05-14V4L/DVB (7851): Fix FW_LOADER depencency at v4l/dvbMauro Carvalho Chehab
Since: 1) FW_LOADER is defined as: config FW_LOADER tristate "Userspace firmware loading support" depends on HOTPLUG 2) several V4L/DVB driver just selects it; 3) select is not smart enough to auto-select HOTPLUG, if select FW_LOADER. So, All drivers that select FW_LOADER should also depend on HOTPLUG. An easier solution (for the end-user perspective) would be to "select HOTPLUG". However, live is not simple. This would cause recursive dependency issues like this one: drivers/usb/Kconfig:62:error: found recursive dependency: USB -> USB_OHCI_HCD -> I2C -> MEDIA_TUNER -> MEDIA_TUNER_XC2028 -> HOTPLUG -> PCCARD -> PCMCIA -> USB_ARCH_HAS_HCD -> MOUSE_APPLETOUCH -> USB Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

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().

2007-10-09V4L/DVB (5997): cx25840: fix audio mute handling and reportingHans Verkuil
Audio muting for the tuner input was implemented by stopping the audio microcontroller and restarting it on unmute. However, it appears that this method can actually crash the audio firmware. It's rare and seems to happen with NTSC only. It has been reimplemented by setting to volume to 0. In addition, the reporting of the mute state has been improved as well: it used to be impossible to detect whether the audio was muted by the user or if it was muted due to the microcontroller trying to detect the audio standard. This is now clearly stated. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-09V4L/DVB (5993): cx25840: resetting also requires reloading the firmwareHans Verkuil

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>
