	bool "Platform Communication Channel Driver"
	depends on ACPI
	default n
	help
	  ACPI 5.0+ spec defines a generic mode of communication
	  between the OS and a platform such as the BMC. This medium
	  (PCC) is typically used by CPPC (ACPI CPU Performance management),
	  RAS (ACPI reliability protocol) and MPST (ACPI Memory power
	  states). Select this driver if your platform implements the
	  PCC clients mentioned above.

	  hardware for interprocessor communication.

config TI_MESSAGE_MANAGER
	tristate "Texas Instruments Message Manager Driver"
	depends on ARCH_KEYSTONE
	help
	  An implementation of Message Manager slave driver for Keystone
	  architecture SoCs from Texas Instruments. Message Manager is a
	  communication entity found on few of Texas Instrument's keystone
	  architecture SoCs. These may be used for communication between
	  multiple processors within the SoC. Select this driver if your
	  platform has support for the hardware block.

config HI6220_MBOX
	tristate "Hi6220 Mailbox"
	depends on ARCH_HISI
	help
	  An implementation of the hi6220 mailbox. It is used to send message
	  between application processors and MCU. Say Y here if you want to
	  build Hi6220 mailbox controller driver.

config MAILBOX_TEST
	tristate "Mailbox Test Client"
	depends on OF
	depends on HAS_IOMEM
	help
	  Test client to help with testing new Controller driver
	  implementations.
