Hi Philipp,

As I'm reading up on the coda driver a little, I can't seem to find the
vendor's sources for the coda_regs.h definitions. Could you point me to
them?

As they don't seem to be in the imx reference manual nor the vpu API
manual, I think it would be worth including a comment about the source
in the header file.

and thanks for this driver. It seems to make the best possible use of
this remaining firmware binary, really :)

I don't know for sure what information Javier based the CodaDx6 register
names on, but I assume that he used the old LGPLed i.MX VPU libraries
that Freescale once distributed. At least that's what I looked at for
the CODA960 additions: The BSP "L3.0.35_12.09.01.01_GA_source.tar.gz"
contained a tarball "pkgs/imx-lib-12.09.01.tar.gz" with a header file
"imx-lib-12.09.01/vpu/vpu_reg.h" inside. I believe the current BSP
versions distributed by NXP do not include this library anymore.

regards
Philipp

Great! Thanks for the details.
