I'm not familiar with genirq/irq_chip. But yes, as Archit said, we can
mask/unmask DSS interrupts. I mean, there's only one interrupt line, but
DSS has irqstatus and irqenable registers that can be used.
If I understood

yes it is. Then it makes sense to have an irq_chip for those two irqs, I
think.
/proc/interrupt will reflect how the hardware works (DSI and DISPC IRQs
being handled by DSS), both dsi and dispc can use normal request_irq()

Hi,

Is it okay to have the same irq entry for 2 different hwmods?
This requirement comes from OMAP3 where dispc and dsi have a common irq
line, where as on OMAP4 dispc and dsi have separate irq lines.
Well, no. I explained that in one of my comment about hwmod modification.
