| depends on SPI_MASTER && OF |
| 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. |

| 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). |

| depends on OF && PM |
| 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. |
| An example of such a bus controller is the Renesas Bus State |
| Controller (BSC, sometimes called "LBSC within Bus Bridge", or |
| "External Bus Interface") as found on several Renesas ARM SoCs. |
