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. |

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. |

|
their settings. For example the GPIOs on Mox SFP module are |
|
configured through this bus. |

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). |

Driver for transparent busses that don't need a real driver, but |

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. |
