Help text

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.
