[RFC PATCH v3 0/2] v4l2-ctrls: add auto focus mode and controls

["Kim, HeungJun" <riverful.kim@samsung.com>]

Hello,

This is third version of RFC patch series about adding auto focus mode
and controls. The patch of the previous version bring about the issue
to be able to execute only once, not repeatedly. Because the each modes
are defined by menu type. To solve this, we add the new control of
choosing focus mode, and if doing repeatedly, it's alright that you
determine the focus mode and change the value of V4L2_CID_FOCUS_AUTO.

In the case of new added rectangle mode, these each controls belongs to
4 new controls, can make to point by the form of rectangle. These 4 new
each control values mean left x coordinate, top y coordinate,
width x length, height y length. It's similar to structure v4l2_rect.

You can find previous threads about this:

Thanks and Regards,
