| config BT1_APB |
| bool "Baikal-T1 APB-bus driver" |
| depends on MIPS_BAIKAL_T1 || COMPILE_TEST |
| select REGMAP_MMIO |
| help |
| Baikal-T1 AXI-APB bridge is used to access the SoC subsystem CSRs. |
| IO requests are routed to this bus by means of the DW AMBA 3 AXI |
| Interconnect. In case of any APB protocol collisions, slave device |
| not responding on timeout an IRQ is raised with an erroneous address |
| reported to the APB terminator (APB Errors Handler Block). This |
| driver provides the interrupt handler to detect the erroneous |
| address, prints an error message about the address fault, updates an |
| errors counter. The counter and the APB-bus operations timeout can be |
| accessed via corresponding sysfs nodes. |
| |
| config BT1_AXI |

| select MFD_SYSCON |
| help |
| AXI3-bus is the main communication bus connecting all high-speed |
| peripheral IP-cores with RAM controller and with MIPS P5600 cores on |
| Baikal-T1 SoC. Traffic arbitration is done by means of DW AMBA 3 AXI |
| Interconnect (so called AXI Main Interconnect) routing IO requests |
| from one SoC block to another. This driver provides a way to detect |
| any bus protocol errors and device not responding situations by |
| means of an embedded on top of the interconnect errors handler |
| block (EHB). AXI Interconnect QoS arbitration tuning is currently |
| unsupported. |

| 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. |

| 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). |

| 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. |

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