[PATCH v3 5/6] bus: Add Baikal-T1 APB-bus driver

2020-05-26 Thread Serge Semin
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 if an attempted APB transaction stays with no response for a pre-defined time an interrupt occurs and the bus gets freed for a next operation.
