If so, dev_id should be added. But sorry, could you let me know
what other interrupt sources are shared with the line?

TRM, GPMC_IRQ is the only source of MA_IRQ_20 for Cortex-A9 MPU
INTC.  Even though GPMC_IRQ is connected with D_IRQ_59(DSP INTC)
and MA_IRQ_20(MPU INTC), this still means it is not a shared line for
MPU INTC.

Also looks the above is similar for OMAP3.

Correct me if the above is wrong.
