  config SH_INTC
  	def_bool y
  	select IRQ_DOMAIN
  
  comment "Interrupt controller options"
  
  config INTC_USERIMASK
  	bool "Userspace interrupt masking support"
  	depends on ARCH_SHMOBILE || (SUPERH && CPU_SH4A)
  	help
  	  This enables support for hardware-assisted userspace hardirq
  	  masking.
  
  	  SH-4A and newer interrupt blocks all support a special shadowed
  	  page with all non-masking registers obscured when mapped in to
  	  userspace. This is primarily for use by userspace device
  	  drivers that are using special priority levels.
  
  	  If in doubt, say N.
  
  config INTC_BALANCING
  	bool "Hardware IRQ balancing support"
  	depends on SMP && SUPERH && CPU_SHX3
  	help
  	  This enables support for IRQ auto-distribution mode on SH-X3
  	  SMP parts. All of the balancing and CPU wakeup decisions are
  	  taken care of automatically by hardware for distributed
  	  vectors.
  
  	  If in doubt, say N.
  
  config INTC_MAPPING_DEBUG
  	bool "Expose IRQ to per-controller id mapping via debugfs"
  	depends on DEBUG_FS
  	help
  	  This will create a debugfs entry for showing the relationship
  	  between system IRQs and the per-controller id tables.
  
  	  If in doubt, say N.
