[media] v4l2-ctls: don't document v4l2_ctrl_fill()

2015-08-22T12:05:51+00:00

This is an obsolete function that has several missing arguments: Warning(.//include/media/v4l2-ctrls.h:340): No description found for parameter 'id' Warning(.//include/media/v4l2-ctrls.h:340): No description found for parameter 'name' Warning(.//include/media/v4l2-ctrls.h:340): No description found for parameter 'type' Warning(.//include/media/v4l2-ctrls.h:340): No description found for parameter 'min' Warning(.//include/media/v4l2-ctrls.h:340): No description found for parameter 'max' Warning(.//include/media/v4l2-ctrls.h:340): No description found for parameter 'step' Warning(.//include/media/v4l2-ctrls.h:340): No description found for parameter 'def' Warning(.//include/media/v4l2-ctrls.h:340): No description found for parameter 'flags' However, this is an obsolete function that should be removed soon. And are not meant to be used anymore. So, instead of documenting those stuff, let's just make DocBook to not handle it, by replacing "/**" by "/*".

[media] v4l2-ctrls.h: add to device-drivers DocBook

2015-08-22T12:05:50+00:00

The comments there are using a wrong format. Due to that, DocBook were unable to parse it. Fix the tags format, and add it to device-drivers.xml. Signed-off-by: Mauro Carvalho Chehab Acked-by: Jonathan Corbet

[media] v4l2-ctrl: move function prototypes from common.h to ctrls.h

2014-11-25T10:24:10+00:00

For some unknown reason several control prototypes where in v4l2-common.c instead of in v4l2-ctrls.h. Move them and document them. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-ctrls: add new RDS TX controls

2014-07-25T22:26:14+00:00

The si4713 supports several RDS features not yet implemented in the driver. This patch adds the missing RDS functionality to the list of RDS controls. The ALT_FREQS control is a compound control containing an array of up to 25 (the maximum according to the RDS standard) frequencies. To support that the V4L2_CTRL_TYPE_U32 was added.

[media] v4l2-ctrls: add support for setting string controls

2014-07-25T22:18:51+00:00

Rather than always having to use a v4l2_ext_control struct to set a control value from within a driver, switch to just setting the new value. This is faster and it makes it possible to set more complex types such as a string control as is added by this patch. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l: ctrls: Unlocked variants of v4l2_ctrl_s_ctrl{,_int64}()

2014-07-21T23:10:48+00:00

Implement unlocked variants of v4l2_ctrl_s_ctrl() and v4l2_ctrl_s_ctrl_int64(). As drivers need to set controls as they access driver internal state elsewhere than in the control framework unlocked variants of these functions become handy.

[media] v4l: ctrls: Provide an unlocked variant of v4l2_ctrl_modify_range()

2014-07-21T22:44:45+00:00

Drivers may use the v4l2_ctrl_modify_range() internally as part of other operations that need to be both serialised using a driver's lock which can also be used to serialise access to the control handler. Provide an unlocked version of the function, __v4l2_ctrl_modify_range() which then may be used by drivers for the purpose.

[media] v4l: ctrls: Move control lock/unlock above the control access functions

2014-07-21T22:43:03+00:00

The v4l2_ctrl_{,un}lock will be needed elsewhere. Define them before the functions that perform operations on controls. Signed-off-by: Sakari Ailus Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-ctrls/videodev2.h: add u8 and u16 types

2014-07-17T14:57:25+00:00

These are needed by the upcoming patches for the motion detection matrices. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
