[media] v4l2-ctrls: remove unclaimed v4l2_ctrl_add_ctrl() interface

2016-02-10T11:34:00+00:00

v4l2_ctrl_add_ctrl() interface has no users since its introduction in commit 0996517cf8ea ("V4L/DVB: v4l2: Add new control handling framework") and its functionality is covered by v4l2_ctrl_new() and derivative interfaces, so it is safe to remove the interface from the kernel.

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

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

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

[media] v4l2-ctrls: add a notify callback

2013-01-05T02:49:54+00:00

Sometimes platform/bridge drivers need to be notified when a control from a sub-device changes value. In order to support this a notify callback was added.

[media] v4l2-ctrls: add a filter function to v4l2_ctrl_add_handler

2012-10-01T20:07:07+00:00

With a filter function you can control more precisely which controls are added. This is useful in particular for radio device nodes for combined TV/Radio cards where you want to show just the radio-specific controls and not controls like brightness.

[media] V4L: Add helper function for standard integer menu controls

2012-05-14T17:03:21+00:00

This patch adds v4l2_ctrl_new_int_menu() helper function which can be used in drivers for creating standard integer menu control with driver-specific menu item list. It is similar to v4l2_ctrl_new_std_menu(), except it doesn't have a mask parameter and an additional qmenu parameter allows passing an array of signed 64-bit integers as the menu item list.
