Currently, the core DSS platform device requests for an irq line for OMAP2 and OMAP3. Make DISPC and DSI platform devices request for a shared IRQ line. On OMAP3, the logical OR of DSI and DISPC interrupt lines goes to the MPU. There is a register DSS_IRQSTATUS which tells if the interrupt came from DISPC or DSI. On OMAP2, there is no DSI, only DISPC interrupts goto the MPU. There is no DSS_IRQSTATUS register. Hence, it makes more sense to have separate irq handlers corresponding to the DSS sub modules instead of having a common handler. Since on OMAP3 the logical OR of the lines goes to MPU, the irq line is shared among the IRQ handlers. The hwmod irq info has been removed for DSS to DISPC and DSI for OMAP2 and OMAP3 hwmod databases. The Probes of DISPC and DSI now request for irq handlers. Signed-off-by: Archit Taneja<archit@xxxxxx> --- v3: -return IRQ_NONE instead of IRQ_HANDLED when interrupt is not ours -don't print module names wehn using DSSERR v2: Removed checking with DSS_IRQSTATUS. v3 tested on 3430sdp with sharp ls panel and 3430sdp with a Taal panel.
