Would it help if I send a patch as a suggestion and as basis for discussion?

Hi all,
Long time ago, TI shipped a kernel named
linux-2.6.32.17-psp03.01.01.39 with an additional kernel option
for scheduling of interrupt endpoints.
AFAIK, this seems to be the only possibility to attach more that 4 in
endpoints to MUSB (at least on a DM368).
This feature reserves one hardware endpoint unit to time schedule
interrupt in endpoints based
on its bInterval value triggered by the SOF interrupt.
I didn't find any discussion about adding such a feature to the
mainline kernel.
IMHO, this feature is absolutely necessary. But there may be reasons,
not to add it (e.g. CPU load).
Please let me know your thoughts and ideas.
Best regards
-Carsten
