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).

106 tristate "Simple Power-Managed Bus Driver"
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
115 "External Bus Interface") as found on several Renesas ARM SoCs.
