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).

Geert Uytterhoeven89d463e2015-02-05 11:11:28 +0100115 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.
