from the Reference Manual, which should be a good starting point for
you, I could see that the IPU (image processing unit) within the i.MX6
SoCs seems to be the same, or at least very similar to the one within
the i.MX53. A driver providing limited functionality of the IPU can be
found in Genode's os repository [2]. The driver however does not
implement the whole operation modes of the IPU, but was developed using
traces regarding I/O memory access of the corresponding Linux kernel
driver, the same approach Martin Stein explained in a previous mail.
Nevertheless, that code might be a good starting point too.

Regards
Stefan
