Subject: [PATCH 4/5] MIPS: BCM63XX: wire up BCM6358's external interrupts 4
|
||
|
|
and 5
|
||
|
|
|
||
|
|
Due to the external interrupts being non consecutive, the previous
|
||
|
|
implementation did not support them. Now that we treat both registers
|
||
|
|
as separate irq controllers, there is no such limitation anymore and
|
||
|
|
we can expose them for drivers to use.
