config CONFIG_ARM_CCI
	bool

config CONFIG_ARM_CCI400_COMMON
	bool
	select CONFIG_ARM_CCI

config CONFIG_ARM_CCI400_PORT_CTRL
	bool
	depends on CONFIG_ARM && CONFIG_OF && CONFIG_CPU_V7
	select CONFIG_ARM_CCI400_COMMON
	help
	  Low level power management driver for CCI400 cache coherent
	  interconnect for CONFIG_ARM platforms.

config CONFIG_BRCMSTB_GISB_ARB
	bool "Broadcom STB GISB bus arbiter"
	depends on CONFIG_ARM || CONFIG_ARM64 || CONFIG_MIPS
	default CONFIG_ARCH_BRCMSTB || CONFIG_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 CONFIG_MOXTET
	tristate "CZ.NIC Turris Mox module configuration bus"
	depends on CONFIG_SPI_MASTER && CONFIG_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 CONFIG_SFP module are
	  configured through this bus.

config CONFIG_HISILICON_LPC
	bool "Support for ISA I/O space on HiSilicon Hip06/7"
	depends on CONFIG_ARM64 && (CONFIG_ARCH_HISI || CONFIG_COMPILE_TEST)
	select CONFIG_INDIRECT_PIO
	help
	  Driver to enable I/O access to devices attached to the Low Pin
	  Count bus on the HiSilicon Hip06/7 SoC.

config CONFIG_IMX_WEIM
	bool "Freescale EIM DRIVER"
	depends on CONFIG_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 CONFIG_MIPS_CDMM
	bool "MIPS Common Device Memory Map (CDMM) Driver"
	depends on CONFIG_CPU_MIPSR2
	help
	  Driver needed for the CONFIG_MIPS Common Device Memory Map bus in CONFIG_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 CONFIG_MVEBU_MBUS
	bool
	depends on CONFIG_PLAT_ORION
	help
	  Driver needed for the MBus configuration on Marvell EBU SoCs
	  (Kirkwood, Dove, Orion5x, MV78XX0 and Armada 370/XP).

config CONFIG_OMAP_INTERCONNECT
	tristate "OMAP INTERCONNECT DRIVER"
	depends on CONFIG_ARCH_OMAP2PLUS

	help
	  Driver to enable OMAP interconnect error handling driver.

config CONFIG_OMAP_OCP2SCP
	tristate "OMAP OCP2SCP DRIVER"
	depends on CONFIG_ARCH_OMAP2PLUS
	help
	  Driver to enable ocp2scp module which transforms ocp interface
	  protocol to scp protocol. In OMAP4, CONFIG_USB PHY is connected via
	  OCP2SCP and in OMAP5, both CONFIG_USB PHY and SATA PHY is connected via
	  OCP2SCP.

config CONFIG_QCOM_EBI2
	bool "Qualcomm External Bus Interface 2 (EBI2)"
	depends on CONFIG_HAS_IOMEM
	depends on CONFIG_ARCH_QCOM || CONFIG_COMPILE_TEST
	default CONFIG_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,
	  CONFIG_SRAM, ethernet adapters, FPGAs and LCD displays.

config CONFIG_SIMPLE_PM_BUS
	tristate "Simple Power-Managed Bus Driver"
	depends on CONFIG_OF && CONFIG_PM
	help
	  Driver for transparent busses that don't need a real driver, but
	  where the bus controller is part of a CONFIG_PM domain, or under the control
	  of a functional clock, and thus relies on runtime CONFIG_PM for managing
	  this CONFIG_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 CONFIG_ARM SoCs.

config CONFIG_SUN50I_DE2_BUS
	bool "Allwinner A64 DE2 Bus Driver"
	  default CONFIG_ARM64
	  depends on CONFIG_ARCH_SUNXI
	  select CONFIG_SUNXI_SRAM
	  help
	  Say y here to enable support for Allwinner A64 DE2 bus driver. It's
	  mostly transparent, but a CONFIG_SRAM region needs to be claimed in the CONFIG_SRAM
	  controller to make the all blocks in the DE2 part accessible.

config CONFIG_SUNXI_RSB
	tristate "Allwinner sunXi Reduced Serial Bus Driver"
	  default CONFIG_MACH_SUN8I || CONFIG_MACH_SUN9I || CONFIG_ARM64
	  depends on CONFIG_ARCH_SUNXI
	  select CONFIG_REGMAP
	  help
	  Say y here to enable support for Allwinner's Reduced Serial Bus
	  (RSB) support. This controller is responsible for communicating
	  with various RSB based devices, such as AXP223, AXP8XX PMICs,
	  and AC100/AC200 ICs.

config CONFIG_TEGRA_ACONNECT
	tristate "Tegra ACONNECT Bus Driver"
	depends on CONFIG_ARCH_TEGRA_210_SOC
	depends on CONFIG_OF && CONFIG_PM
	select CONFIG_PM_CLK
	help
	  Driver for the Tegra ACONNECT bus which is used to interface with
	  the devices inside the Audio Processing Engine (APE) for Tegra210.

	tristate "Tegra Generic Memory Interface bus driver"
	depends on CONFIG_ARCH_TEGRA
	help
	  Driver for the Tegra Generic Memory Interface bus which can be used
	  to attach devices such as NOR, UART, CONFIG_FPGA and more.

config CONFIG_TI_SYSC
