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).

125	  Driver for transparent busses that don't need a real driver, but
126	  where the bus controller is part of a PM domain, or under the control
127	  of a functional clock, and thus relies on runtime PM for managing
128	  this PM domain and/or clock.
129	  An example of such a bus controller is the Renesas Bus State
130	  Controller (BSC, sometimes called "LBSC within Bus Bridge", or
