the whole omap_irq_fifo_underflow() and omap_irq_ocp_error_handler() IRQ handling to the DSS side, as they're not DRM/KMS-related ?

I think we should react to both errors somehow (I'm not sure how, disable output probably), and that has to be done on the KMS level. We don't do that now, but moving this to DSS side would make error handling more difficult to do in the future.

Ideally I'd demultiplex interrupts on the DSS side and report events to the KMS side (page flip completion, underflows, ...).
