23	select ARM_CCI_PMU
24	help
25	  Support for PMU events monitoring on the ARM CCI-400 (cache coherent
26	  interconnect). CCI-400 supports counting events related to the
27	  connected slave/master interfaces.

34	  Low level power management driver for CCI400 cache coherent
35	  interconnect for ARM platforms.

41	depends on PERF_EVENTS
42	select ARM_CCI_PMU
43	help
44	  Support for PMU events monitoring on the ARM CCI-500 cache coherent
45	  interconnect. CCI-500 provides 8 independent event counters, which
46	  can count events pertaining to the slave/master interfaces as well
47	  as the internal events to the CCI.
48
49	  If unsure, say Y

51config ARM_CCN
52	bool "ARM CCN driver support"
53	depends on ARM || ARM64
54	depends on PERF_EVENTS
55	help
56	  PMU (perf) driver supporting the ARM CCN (Cache Coherent Network)
57	  interconnect.

59config BRCMSTB_GISB_ARB
60	bool "Broadcom STB GISB bus arbiter"
61	depends on ARM || MIPS
62	help
63	  Driver for the Broadcom Set Top Box System-on-a-chip internal bus
64	  arbiter. This driver provides timeout and target abort error handling
65	  and internal bus master decoding.
66
67config IMX_WEIM
68	bool "Freescale EIM DRIVER"
69	depends on ARCH_MXC
70	help
71	  Driver for i.MX WEIM controller.
72	  The WEIM(Wireless External Interface Module) works like a bus.
73	  You can attach many different devices on it, such as NOR, onenand.
74
75config MIPS_CDMM
76	bool "MIPS Common Device Memory Map (CDMM) Driver"
77	depends on CPU_MIPSR2
78	help
79	  Driver needed for the MIPS Common Device Memory Map bus in MIPS
80	  cores. This bus is for per-CPU tightly coupled devices such as the
81	  Fast Debug Channel (FDC).
82
83	  For this to work, either your bootloader needs to enable the CDMM
84	  region at an unused physical address on the boot CPU, or else your
85	  platform code needs to implement mips_cdmm_phys_base() (see
86	  asm/cdmm.h).
87
88config MVEBU_MBUS
89	bool
90	depends on PLAT_ORION
91	help
92	  Driver needed for the MBus configuration on Marvell EBU SoCs
93	  (Kirkwood, Dove, Orion5x, MV78XX0 and Armada 370/XP).
94
95config OMAP_INTERCONNECT
96	tristate "OMAP INTERCONNECT DRIVER"
97	depends on ARCH_OMAP2PLUS
98
99	help
100	  Driver to enable OMAP interconnect error handling driver.
101
102config OMAP_OCP2SCP
103	tristate "OMAP OCP2SCP DRIVER"
104	depends on ARCH_OMAP2PLUS
105	help
106	  Driver to enable ocp2scp module which transforms ocp interface
107	  protocol to scp protocol. In OMAP4, USB PHY is connected via
108	  OCP2SCP and in OMAP5, both USB PHY and SATA PHY is connected via
109	  OCP2SCP.

111config SIMPLE_PM_BUS
112	bool "Simple Power-Managed Bus Driver"
113	depends on OF && PM
114	depends on ARCH_SHMOBILE || COMPILE_TEST
115	help
116	  Driver for transparent busses that don't need a real driver, but
117	  where the bus controller is part of a PM domain, or under the control
118	  of a functional clock, and thus relies on runtime PM for managing
119	  this PM domain and/or clock.
120	  An example of such a bus controller is the Renesas Bus State
121	  Controller (BSC, sometimes called "LBSC within Bus Bridge", or
122	  "External Bus Interface") as found on several Renesas ARM SoCs.
123
124config VEXPRESS_CONFIG

129	select REGMAP
130	help
131	  Platform configuration infrastructure for the ARM Ltd.
132	  Versatile Express.
