79 help
80 Driver needed for the MIPS Common Device Memory Map bus in MIPS
81 cores. This bus is for per-CPU tightly coupled devices such as the
82 Fast Debug Channel (FDC).
83
84 For this to work, either your bootloader needs to enable the CDMM
85 region at an unused physical address on the boot CPU, or else your
86 platform code needs to implement mips_cdmm_phys_base() (see
87 asm/cdmm.h).

123 bool "Simple Power-Managed Bus Driver"
124 depends on OF && PM
125 help
126 Driver for transparent busses that don't need a real driver, but
127 where the bus controller is part of a PM domain, or under the control
128 of a functional clock, and thus relies on runtime PM for managing
129 this PM domain and/or clock.
130 An example of such a bus controller is the Renesas Bus State
131 Controller (BSC, sometimes called "LBSC within Bus Bridge", or
132 "External Bus Interface") as found on several Renesas ARM SoCs.
