Hi,

From the discussions on the GStreamer focus controls thread [1], we decided to
define a default behaviour for camera startup to be handled by the IPA.

This series explicitly defines a default behaviour by requiring the IPA put the
lens to the position given by the controls::LensPosition default value.
Typically this would be the hyperfocal position.  Patch 1 updates the controls
documentation, while patches 2 and 3 make the necessary changes to the RPi IPA
to move the lens on the first call to ipa->configure().

Regards,
Naush
