I don't know how DSS_IRQSTATUS works under the hood, but be > careful of such assumptions :-) That's how DISPC_IRQ* and DSI_IRQ* also works. But that's not what this discussion was about =). DISPC and DSI have a shared interrupt line, and there's a DSS_IRQSTATUS register with two bits, telling if the interrupt was for DISPC or DSI.
