| config MIPS_CDMM |
| bool "MIPS Common Device Memory Map (CDMM) Driver" |
| depends on CPU_MIPSR2 |
| 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. |
| 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. |
