Hi,

This patch set implements UVC v1.5 region of interest using V4L2
control API.

ROI control is consisted two uvc specific controls.
1. A rectangle control with a newly added type V4L2_CTRL_TYPE_RECT.
2. An auto control with type bitmask.

V4L2_CTRL_WHICH_MIN/MAX_VAL is added to support the rectangle control.

The corresponding v4l-utils series can be found at
https://patchwork.linuxtv.org/project/linux-media/list/?series=11069 .

Tested with v4l2-compliance, v4l2-ctl, calling ioctls on usb cameras and
VIVID with a newly added V4L2_CTRL_TYPE_RECT control.
