 66           For this to work, either your bootloader needs to enable the CDMM
 67           region at an unused physical address on the boot CPU, or else your
 68           platform code needs to implement mips_cdmm_phys_base() (see
 69           asm/cdmm.h).

 99           Driver for transparent busses that don't need a real driver, but
100           where the bus controller is part of a PM domain, or under the control
101           of a functional clock, and thus relies on runtime PM for managing
102           this PM domain and/or clock.
103           An example of such a bus controller is the Renesas Bus State
104           Controller (BSC, sometimes called "LBSC within Bus Bridge", or
105           "External Bus Interface") as found on several Renesas ARM SoCs.
