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

2014-11-25T10:24:10Z

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

2014-07-25T22:26:14Z

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

2014-07-25T22:18:51Z

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}()

2014-07-21T23:10:48Z

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()

2014-07-21T22:44:45Z

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

2014-07-21T22:43:03Z

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

[media] v4l2-ctrls: use ptrs for all but the s32 type

2014-07-17T14:57:17Z

Rather than having two unions for all types just keep 'val' and 'cur.val' and use the p_cur and p_new unions to access all others. The only reason for keeping 'val' and 'cur.val' is that it is used all over, so converting this as well would be a huge job. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
