2009-04-28cx88: Fix race condition between cx8800 startup and haldDevin Heitmueller
From: Devin Heitmueller <dheitmueller@kernellabs.com> A power management fix to properly put the xc5000 into low power mode revealed a race condition where hald could detect the creation of the device file and connect to the device while the initial device configuration is still in progress. Lock the core structure so that video_release cannot be called and put the tuner to sleep in the middle of the initial call to cx88_set_tvnorm() in cx8800_initdev() Thanks to Michael Krufky for discovering the issue and providing an environment to test in.

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>

2009-04-01v4l2-common: add explicit v4l2_device pointer as first arg to ↵Hans Verkuil
new_(probed)_subdev From: Hans Verkuil <hverkuil@xs4all.nl> The functions v4l2_i2c_new_subdev and v4l2_i2c_new_probed_subdev relied on i2c_get_adapdata to return the v4l2_device. However, this is not always possible on embedded platforms. So modify the API to pass the v4l2_device pointer explicitly. 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>
2009-04-01v4l2-subdev: move s_standby from core to tuner.Hans Verkuil

From: Hans Verkuil <hverkuil@xs4all.nl> Convert cx88 to use v4l2_subdev since the old i2c autoprobing mechanism will be removed. Added code to explicitly load tvaudio where needed. Also fix the rtc-isl1208 support: since that driver no longer supports autoprobing it has to be loaded using the new i2c API. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2009-03-03cx88: Don't need to zero ioctl parameter fieldsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The v4l2 core code in v4l2_ioctl will zero out the structure the driver is supposed to fill in for read-only ioctls. For read/write ioctls, all the fields which aren't supplied from userspace will be zeroed out. Zeroing code is removed from enum_input and g_tuner.

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.

2008-12-30v4l2: introduce v4l2_file_operations.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.

2008-10-19v4l: use video_device.num instead of minor in video%dHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now independent of the minor number. So instead of using the minor field of the video_device struct one has to use the num field: this always contains the kernel number of the device node. I forgot about this when I did the v4l2 core change, so this patch converts all drivers that use it in one go. Luckily the change is trivial.

From: Darron Broad <darron@kewl.org> This adds I2S-ADC tvaudio mode as a formal method of audio delivery. This fixes one bug and adds fm audio via I2S-ADC on cards that support it. The bug occured before when I2S-ADC mode was initiated on composite/s-video open but was then reset within 500ms by the audio thread which used any previous audio tuning details.

2008-07-30v4l: move BKL down to the driver level.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The BKL is now moved from the video_open function in v4l2-dev.c to the various drivers. It seems about a third of the drivers already has a lock of some sort protecting the open(), another third uses video_exclusive_open (yuck!) and the last third required adding the BKL in their open function.

2008-07-26v4l2-dev: remove unused type and type2 field from video_deviceHans Verkuil

2008-07-21videodev: move all ioctl callbacks to a new v4l2_ioctl_ops structHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> All ioctl callbacks are now stored in a new v4l2_ioctl_ops struct. Drivers fill in a const struct v4l2_ioctl_ops and video_device just contains a const pointer to it. This ensures a clean separation between the const ops struct and the non-const video_device struct.

From: Hans Verkuil <hverkuil@xs4all.nl> The functions in a header should not belong to another module. The prio functions belong to v4l2-common.c, so move them to v4l2-common.h. The ioctl functions belong to v4l2-ioctl.c, so create a new v4l2-ioctl.h header and move those functions to it. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

2007-10-17Don't limit cx88 audio routing to blackbird boardsRicardo Cerqueira
From: Ricardo Cerqueira <v4l@cerqueira.org> All cx2388 boards need the line-in audio to be routed from an external ADC (refered to as "ADC mode" in the spec sheet), since the chip is uncapable of dealing with baseband audio directly. So... this patch enables normal mode when using the tuner (TV or Radio), and enables ADC mode with any other source. It'll probably only work with boards that have supported ADCs (such as the Wolfson wm9775) Signed-off-by: Ricardo Cerqueira <v4l@cerqueira.org>

From: Ricardo Cerqueira <v4l@cerqueira.org> Fix lack of audio on the MPEG-2 stream of wm8775 based blackbirds. The wm8775 module initializes the audio input at "route 2", which doesn't hold true for all boards. The HVR-1300, for example, uses route 1 for tuner audio, and route 2 for baseband. So we must route the audio to the proper input depending on what video input is being used. Signed-off-by: Ricardo Cerqueira <v4l@cerqueira.org> Signed-off-by: Michael Krufky <mkrufky@linuxtv.org>
