| help | |
| Say yes here to add support for the module configuration bus found | |
| on CZ.NIC's Turris Mox. This is needed for the ability to discover | |
| the order in which the modules are connected and to get/set some of | |
| their settings. For example the GPIOs on Mox SFP module are | |
| configured through this bus. | |

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

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

| Controller (BSC, sometimes called "LBSC within Bus Bridge", or | |
| "External Bus Interface") as found on several Renesas ARM SoCs. | |
