  4. Subject: [PATCH 4/5] MIPS: BCM63XX: wire up BCM6358's external interrupts 4
    5. 

  5.  and 5
    6. 

  6. 

  7. Due to the external interrupts being non consecutive, the previous
    8. 

  8. implementation did not support them. Now that we treat both registers
    9. 

  9. as separate irq controllers, there is no such limitation anymore and
    10. 

  10. we can expose them for drivers to use.
    11.
