[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.

never done.

[media] v4l2-ctrls: v4l2_ctrl_handler_setup must set is_new to 1

2011-01-19T13:45:32+00:00

Renamed has_new to is_new.

Drivers can use the is_new field to determine if a new value was specified
for a control. The v4l2_ctrl_handler_setup() must always set this to 1 since
the setup has to force a full update of all controls.
