24    * - Flag name
25      - id
26      - Definition
27      - Valid for V4L2
28      - Valid for V4L2 subdev
29    * - ``V4L2_SEL_FLAG_GE``
30      - (1 << 0)
31      - Suggest the driver it should choose greater or equal rectangle (in
32	size) than was requested. Albeit the driver may choose a lesser
33	size, it will only do so due to hardware limitations. Without this
34	flag (and ``V4L2_SEL_FLAG_LE``) the behaviour is to choose the
35	closest possible rectangle.
36      - Yes
37      - Yes
38    * - ``V4L2_SEL_FLAG_LE``
39      - (1 << 1)
40      - Suggest the driver it should choose lesser or equal rectangle (in
41	size) than was requested. Albeit the driver may choose a greater
42	size, it will only do so due to hardware limitations.
43      - Yes
44      - Yes
45    * - ``V4L2_SEL_FLAG_KEEP_CONFIG``
46      - (1 << 2)
47      - The configuration must not be propagated to any further processing
48	steps. If this flag is not given, the configuration is propagated
49	inside the subdevice to all further processing steps.
50      - No
51      - Yes
