17    * - Flag name
18      - id
19      - Definition
20      - Valid for V4L2
21      - Valid for V4L2 subdev
22    * - ``V4L2_SEL_FLAG_GE``
23      - (1 << 0)
24      - Suggest the driver it should choose greater or equal rectangle (in
25	size) than was requested. Albeit the driver may choose a lesser
26	size, it will only do so due to hardware limitations. Without this
27	flag (and ``V4L2_SEL_FLAG_LE``) the behaviour is to choose the
28	closest possible rectangle.
29      - Yes
30      - Yes
31    * - ``V4L2_SEL_FLAG_LE``
32      - (1 << 1)
33      - Suggest the driver it should choose lesser or equal rectangle (in
34	size) than was requested. Albeit the driver may choose a greater
35	size, it will only do so due to hardware limitations.
36      - Yes
37      - Yes
38    * - ``V4L2_SEL_FLAG_KEEP_CONFIG``
39      - (1 << 2)
40      - The configuration must not be propagated to any further processing
41	steps. If this flag is not given, the configuration is propagated
42	inside the subdevice to all further processing steps.
43      - No
44      - Yes
