     25      - Definition
     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
