 42	help
 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.

 69	help
 70	  Driver for i.MX WEIM controller.
 71	  The WEIM(Wireless External Interface Module) works like a bus.
 72	  You can attach many different devices on it, such as NOR, onenand.
 73
 74config MIPS_CDMM
 75	bool "MIPS Common Device Memory Map (CDMM) Driver"
 76	depends on CPU_MIPSR2
 77	help
 78	  Driver needed for the MIPS Common Device Memory Map bus in MIPS
 79	  cores. This bus is for per-CPU tightly coupled devices such as the
 80	  Fast Debug Channel (FDC).
 81
 82	  For this to work, either your bootloader needs to enable the CDMM
 83	  region at an unused physical address on the boot CPU, or else your
 84	  platform code needs to implement mips_cdmm_phys_base() (see
 85	  asm/cdmm.h).

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