55
56	  For this to work, either your bootloader needs to enable the CDMM
57	  region at an unused physical address on the boot CPU, or else your
58	  platform code needs to implement mips_cdmm_phys_base() (see
59	  asm/cdmm.h).

98	  Driver for transparent busses that don't need a real driver, but
99	  where the bus controller is part of a PM domain, or under the control
100	  of a functional clock, and thus relies on runtime PM for managing
101	  this PM domain and/or clock.
