77	depends on CPU_MIPSR2
78	help
79	  Driver needed for the MIPS Common Device Memory Map bus in MIPS
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).

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