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

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