config RAPIDIO_DISC_TIMEOUT

	---help---
	  Amount of time a discovery node waits for a host to complete
	  enumeration before giving up.

config RAPIDIO_ENABLE_RX_TX_PORTS
	bool "Enable RapidIO Input/Output Ports"
	depends on RAPIDIO
	---help---
	  The RapidIO specification describes a Output port transmit
	  enable and a Input port receive enable. The recommended state
	  for Input ports and Output ports should be disabled. When
	  this switch is set the RapidIO subsystem will enable all
	  ports for Input/Output direction to allow other traffic
	  than Maintenance transfers.

config RAPIDIO_DMA_ENGINE
	bool "DMA Engine support for RapidIO"
	depends on RAPIDIO
	select DMADEVICES
	select DMA_ENGINE
	help
	  Say Y here if you want to use DMA Engine frameork for RapidIO data
	  transfers to/from target RIO devices. RapidIO uses NREAD and
	  NWRITE (NWRITE_R, SWRITE) requests to transfer data between local
	  memory and memory on remote target device. You need a DMA controller
	  capable to perform data transfers to/from RapidIO.

	  If you are unsure about this, say Y here.

config RAPIDIO_DEBUG
	bool "RapidIO subsystem debug messages"
	depends on RAPIDIO
	help
	  Say Y here if you want the RapidIO subsystem to produce a bunch of
	  debug messages to the system log. Select this if you are having a
	  problem with the RapidIO subsystem and want to see more of what is
	  going on.

	  If you are unsure about this, say N here.

	depends on RAPIDIO
	default RAPIDIO_ENUM_BASIC
	help
	  There are different enumeration and discovery mechanisms offered
	  for RapidIO subsystem. You may select single built-in method or
	  or any number of methods to be built as modules.
	  Selecting a built-in method disables use of loadable methods.

	  If unsure, select Basic built-in.

config RAPIDIO_ENUM_BASIC
	tristate "Basic"
	help
	  This option includes basic RapidIO fabric enumeration and discovery
	  mechanism similar to one described in RapidIO specification Annex 1.

	help
	  This option includes RapidIO channelized messaging driver which

	  messaging mailbox between multiple user-space applications.
	  See "Documentation/driver-api/rapidio/rio_cm.rst" for driver description.

	depends on RAPIDIO
	help
	  This option includes generic RapidIO mport device driver which
	  allows to user space applications to perform RapidIO-specific
	  operations through selected RapidIO mport.
