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