	depends on ARM || ARM64 || MIPS
	default ARCH_BRCMSTB || BMIPS_GENERIC
	help
	  Driver for the Broadcom Set Top Box System-on-a-chip internal bus
	  arbiter. This driver provides timeout and target abort error handling
	  and internal bus master decoding.

config MOXTET
	tristate "CZ.NIC Turris Mox module configuration bus"
	depends on SPI_MASTER && OF
	help
	  Say yes here to add support for the module configuration bus found
	  on CZ.NIC's Turris Mox. This is needed for the ability to discover
	  the order in which the modules are connected and to get/set some of
	  their settings. For example the GPIOs on Mox SFP module are
	  configured through this bus.

config HISILICON_LPC

	  Driver to enable I/O access to devices attached to the Low Pin
	  Count bus on the HiSilicon Hip06/7 SoC.

config IMX_WEIM
	bool "Freescale EIM DRIVER"
	depends on ARCH_MXC
	help
	  Driver for i.MX WEIM controller.
	  The WEIM(Wireless External Interface Module) works like a bus.
	  You can attach many different devices on it, such as NOR, onenand.

config MIPS_CDMM
	bool "MIPS Common Device Memory Map (CDMM) Driver"
	depends on CPU_MIPSR2
	help
	  Driver needed for the MIPS Common Device Memory Map bus in MIPS
	  cores. This bus is for per-CPU tightly coupled devices such as the
	  Fast Debug Channel (FDC).

	  For this to work, either your bootloader needs to enable the CDMM
	  region at an unused physical address on the boot CPU, or else your
	  platform code needs to implement mips_cdmm_phys_base() (see
	  asm/cdmm.h).

config MVEBU_MBUS
	bool
	depends on PLAT_ORION
	help
	  Driver needed for the MBus configuration on Marvell EBU SoCs
	  (Kirkwood, Dove, Orion5x, MV78XX0 and Armada 370/XP).

config OMAP_INTERCONNECT
	tristate "OMAP INTERCONNECT DRIVER"
	depends on ARCH_OMAP2PLUS

	help
	  Driver to enable OMAP interconnect error handling driver.

config OMAP_OCP2SCP
	tristate "OMAP OCP2SCP DRIVER"
	depends on ARCH_OMAP2PLUS
	help
	  Driver to enable ocp2scp module which transforms ocp interface
	  protocol to scp protocol. In OMAP4, USB PHY is connected via
	  OCP2SCP and in OMAP5, both USB PHY and SATA PHY is connected via
	  OCP2SCP.

config QCOM_EBI2
	bool "Qualcomm External Bus Interface 2 (EBI2)"
	depends on HAS_IOMEM
	depends on ARCH_QCOM || COMPILE_TEST
	default ARCH_QCOM
	help
	  Say y here to enable support for the Qualcomm External Bus
	  Interface 2, which can be used to connect things like NAND Flash,
	  SRAM, ethernet adapters, FPGAs and LCD displays.

config SIMPLE_PM_BUS
	tristate "Simple Power-Managed Bus Driver"
	depends on OF && PM
	help
	  Driver for transparent busses that don't need a real driver, but
	  where the bus controller is part of a PM domain, or under the control
	  of a functional clock, and thus relies on runtime PM for managing
	  this PM domain and/or clock.
	  An example of such a bus controller is the Renesas Bus State
	  Controller (BSC, sometimes called "LBSC within Bus Bridge", or
	  "External Bus Interface") as found on several Renesas ARM SoCs.

config SUN50I_DE2_BUS
	bool "Allwinner A64 DE2 Bus Driver"
	  default ARM64
	  depends on ARCH_SUNXI
	  select SUNXI_SRAM
	  help
	  Say y here to enable support for Allwinner A64 DE2 bus driver. It's
	  mostly transparent, but a SRAM region needs to be claimed in the SRAM
	  controller to make the all blocks in the DE2 part accessible.

config SUNXI_RSB
