IMHO DSS2 is also not in the 2.6.28 kernel. You have to use the right
patches or to use Angstrom which has all the patches.
Robert
The kernel has a macro to detect ES revisions, could you use that and
send patch for it?

Isn't B7 and C1 ES3.0 instead of ES3.1?
regards,
Koen
They are. Rev C2 will be ES3.0 as well.
Hi Matthieu,
From where in sprz278.pdf did you get the information, that these registers
would be extended in either ES3.0 or ES3.1?
As I read chapter 2 of this document it just states some limitations of the
OMAP3530 compared to what an ordinary user might expect. I'm *happy* that
you can confirm, that the registers in ES3.0 apparently has been extended,
but I don't like that I can't find this information officially in any
documents - On the contrary I think to find the exact opposite info in
sprz268.pdf - What have I missed? :-)
Best regards and thanks
Søren
I can confirm that the timing registers have been extended on my OMAP
SDP board which has ES3.0. Also the latest TRM has been changed to
reflect the HW change. But I haven't found information about which ES
versions have this change. I guess experiments have proven it to be
ES3.0+ =).
Tomi
To summarize: Great - Meaning Rev B7/C2 support full timing (12/12/8)
although not officially according to TI.
The extended registers are officially first announced/promised in ES3.1, but
seems to be active already in ES3.0 - Right?
@Tomi: Which version of the TRM do you have? The version I have is
inconsistent on this topic as highlighted in my previous post "Re: HDMI
output from Beagle board" around one week ago...
Thanks

I have:
OMAP34xx Multimedia Device
Silicon Revision 3.1
Texas Instruments OMAP™ Family of Products
Version O
Technical Reference Manual
I only now noticed the "silicon revision 3.1" note there. But it _does_
work on my ES3.0 SDP... Probably more testing is needed until we can
really say it works on ES3.0s.
