34	depends on SPI_MASTER && OF
35	help
36	  Say yes here to add support for the module configuration bus found
37	  on CZ.NIC's Turris Mox. This is needed for the ability to discover
38	  the order in which the modules are connected and to get/set some of
39	  their settings. For example the GPIOs on Mox SFP module are
40	  configured through this bus.

63	  cores. This bus is for per-CPU tightly coupled devices such as the
64	  Fast Debug Channel (FDC).
65
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).

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