- Valid for V4L2
- Valid for V4L2 subdev
* - ``V4L2_SEL_FLAG_GE``
- (1 << 0)
- Suggest the driver it should choose greater or equal rectangle (in
size) than was requested. Albeit the driver may choose a lesser
size, it will only do so due to hardware limitations. Without this
flag (and ``V4L2_SEL_FLAG_LE``) the behaviour is to choose the
closest possible rectangle.

- Yes
* - ``V4L2_SEL_FLAG_KEEP_CONFIG``

- The configuration must not be propagated to any further processing
steps. If this flag is not given, the configuration is propagated
inside the subdevice to all further processing steps.
