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

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).

112	bool "Simple Power-Managed Bus Driver"
113	depends on OF && PM
114	depends on ARCH_RENESAS || 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 SUNXI_RSB

129	  help
130	  Say y here to enable support for Allwinner's Reduced Serial Bus
131	  (RSB) support. This controller is responsible for communicating
132	  with various RSB based devices, such as AXP223, AXP8XX PMICs,
133	  and AC100/AC200 ICs.

135# TODO: This uses pm_clk_*() symbols that aren't exported in v4.7 and hence
136# the driver will fail to build as a module. However there are patches to
137# address that queued for v4.8, so this can be turned into a tristate symbol
138# after v4.8-rc1.
