I thought about that, but that would make it impossible to COMPILE_TEST both the
pxa and the soc_camera driver. In addition, the pxa and soc_camera are the only
drivers that use this, and I prefer to just merge that code into pxa so that it
can
be modified independently from soc_camera.
I really want to remove all dependencies to soc_camera. That will also make it
easier
to refactor soc_camera once I get the atmel-isi driver out of soc_camera.
Regards,
Hans
