help
Include shared interrupt support in system. Shared interrupt
support is NOT required in most systems. If in doubt answer no.

int
depends on SHARED_IRQ
prompt "The number of clients per instance"
default 5
help
Configures the maximum nuber of clients allowed per shared
instance of the shared interrupt driver. To conserve RAM set
this value to the lowest practical value.

prompt "Shared IRQ init priority"
help
Shared IRQ are initialized on POST_KERNEL init level. They
have to be initialized before any device that uses them.

help
Provide an instance of the shared interrupt driver when system
configuration requires that multiple devices share an interrupt.
