I haven't been using the parallel interface nor I know anyone else who
would have. Sergio, any idea?
Anyway, this sounds like a problem in the parallel receiver side. You
could try also configuring the VD1 IRQ to happen much earlier, say on
10th line. See ISPCCDC_VDINT handling in ispccdc.c.
I'm going to update the patchset as soon as I get linux-omap booting again.
