25	depends on ARM || ARM64 || MIPS
26	default ARCH_BRCMSTB || BMIPS_GENERIC
27	help
28	  Driver for the Broadcom Set Top Box System-on-a-chip internal bus

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	  Driver needed for the MIPS Common Device Memory Map bus in MIPS
64	  cores. This bus is for per-CPU tightly coupled devices such as the
65	  Fast Debug Channel (FDC).
66
67	  For this to work, either your bootloader needs to enable the CDMM
68	  region at an unused physical address on the boot CPU, or else your
69	  platform code needs to implement mips_cdmm_phys_base() (see
70	  asm/cdmm.h).

107	depends on OF && PM
108	help
109	  Driver for transparent busses that don't need a real driver, but
110	  where the bus controller is part of a PM domain, or under the control
111	  of a functional clock, and thus relies on runtime PM for managing
112	  this PM domain and/or clock.
113	  An example of such a bus controller is the Renesas Bus State
114	  Controller (BSC, sometimes called "LBSC within Bus Bridge", or
