2009-06-09v4l2: add new s_config subdev ops and v4l2_i2c_new_subdev_cfg/board callsHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> Add a new s_config core ops call: this is called with the irq and platform data to be used to initialize the subdev. Added new v4l2_i2c_new_subdev_cfg and v4l2_i2c_new_subdev_board calls that allows you to pass these new arguments. The existing v4l2_i2c_new_subdev functions were modified to also call s_config. In the future the existing v4l2_i2c_new_subdev functions will be replaced by a single v4l2_i2c_new_subdev function similar to v4l2_i2c_new_subdev_cfg but without the irq and platform_data arguments.

2009-05-30v4l2: Create helper function for bounding and aligning imagesTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Most hardware has limits on minimum and maximum image dimensions and also requirements about alignment. For example, image width must be even or a multiple of four. Some hardware has requirements that the total image size (width * height) be a multiple of some power of two. v4l_bound_align_image() will enforce min and max width and height, power of two alignment on width and height, and power of two alignment on total image size. It uses an efficient algorithm that will try to find the "closest" image size that meets the requirements. Priority: normal Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>
2009-05-02v4l2-device: unregister i2c_clients when unregistering the v4l2_device.Mauro Carvalho Chehab
From: Hans Verkuil <hverkuil@xs4all.nl> Until now I relied on i2c_del_adapter to unregister the i2c_clients for me, however, if the i2c bus is a platform bus then it is never deleted. So instead I need to unregister i2c clients when unregistering the v4l2_device.

2009-05-02tuner: remove tuner_i2c_address_checkMauro Carvalho Chehab
From: Hans Verkuil <hverkuil@xs4all.nl> Support for tuners with i2c addresses >= 0x65 is dropped since no tuners with addresses in the range 0x65-0x6f have been found. This patch removes addresses 0x65-0x6f from the list of tuner probe addresses, it removes the kernel warning that warned if addresses in this range appeared, and it removed a hack for the cx88 that is no longer needed now that the tuner address range is reduced.

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>

From: Hans Verkuil <hverkuil@xs4all.nl> Now that all drivers are converted to v4l2_subdev we can remove legacy code in v4l2-common. Also move the documentation of the internal API to v4l2-subdev.h where it really belongs. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>

From: Hans Verkuil <hverkuil@xs4all.nl> The v4l2_ctrl_query_fill_std() function wasn't one the best idea I ever had. It doesn't add anything valuable that cannot be expressed equally well with v4l2_ctrl_query_fill and only adds overhead.

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.

2008-02-02Fix Kconfig dependenciesMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> As pointed by Adrian Bunk, with I2C=m and VIDEO_DEV=y, videodev brokes. This patch moves the functions that videodev needs from v4l2-common. It also fixes some Kconfig changes. After this patch, I2C=m / VIDEO_DEV=y will make v4l2 core statically linked into kernel. v4l2-common will be m, and all V4L drivers will also be m. This approach is very conservative, since it is possible to have V4L drivers that don't need I2C or v4l2-common. The better is to map what drivers really need v4l2-common, making them to select v4l2-common, and allowing the others to be 'y', 'm' and 'n'.
