  	depends on (ARM && CPU_V7) || ARM64
  	depends on PERF_EVENTS
  	select ARM_CCI_PMU
  	help

  	  Support for PMU events monitoring on the ARM CCI-500/CCI-550 cache
  	  coherent interconnects. Both of them provide 8 independent event counters,
  	  which can count events pertaining to the slave/master interfaces as well

  	  as the internal events to the CCI.
  
  	  If unsure, say Y

  config ARM_CCN

  	tristate "ARM CCN driver support"

  	depends on ARM || ARM64
  	depends on PERF_EVENTS
  	help
  	  PMU (perf) driver supporting the ARM CCN (Cache Coherent Network)
  	  interconnect.

  config BRCMSTB_GISB_ARB
  	bool "Broadcom STB GISB bus arbiter"

  	depends on ARM || 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 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

  	depends on HAS_IOMEM

  	depends on ARCH_QCOM || COMPILE_TEST

  	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
  	bool "Simple Power-Managed Bus Driver"
  	depends on OF && PM

  	depends on ARCH_RENESAS || COMPILE_TEST

  	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 SUNXI_RSB
  	tristate "Allwinner sunXi Reduced Serial Bus Driver"
  	  default MACH_SUN8I || MACH_SUN9I
  	  depends on ARCH_SUNXI
  	  select 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 TEGRA_ACONNECT

  	tristate "UniPhier System Bus driver"

  	depends on ARCH_UNIPHIER && OF
  	default y
  	help
  	  Support for UniPhier System Bus, a simple external bus.  This is
  	  needed to use on-board devices connected to UniPhier SoCs.
