bool "ARM CCI400 PMU support"
depends on (ARM && CPU_V7) || ARM64
depends on PERF_EVENTS
select ARM_CCI400_COMMON
select ARM_CCI_PMU
help
Support for PMU events monitoring on the ARM CCI-400 (cache coherent
interconnect). CCI-400 supports counting events related to the
connected slave/master interfaces.
config ARM_CCI400_PORT_CTRL
bool
depends on ARM && OF && CPU_V7
select ARM_CCI400_COMMON
help
Low level power management driver for CCI400 cache coherent
interconnect for ARM platforms.
config ARM_CCI5xx_PMU
bool "ARM CCI-500/CCI-550 PMU support"
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 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.
# TODO: This uses pm_clk_*() symbols that aren't exported in v4.7 and hence
# the driver will fail to build as a module. However there are patches to
# address that queued for v4.8, so this can be turned into a tristate symbol
# after v4.8-rc1.
config TEGRA_ACONNECT
bool "Tegra ACONNECT Bus Driver"
depends on ARCH_TEGRA_210_SOC
depends on OF && PM
select 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.
config UNIPHIER_SYSTEM_BUS
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.
config VEXPRESS_CONFIG
bool "Versatile Express configuration bus"
default y if ARCH_VEXPRESS
depends on ARM || ARM64
depends on OF
select REGMAP
help
Platform configuration infrastructure for the ARM Ltd.
Versatile Express.
