-title: Baikal-T1 PCIe Root Port Controller
-
-maintainers:
-  - Serge Semin <[email protected]>
-
-description:
-  Embedded into Baikal-T1 SoC Root Complex controller with a single port
-  activated. It's based on the DWC RC PCIe v4.60a IP-core, which is configured
-  to have just a single Root Port function and is capable of establishing the
-  link up to Gen.3 speed on x4 lanes. It doesn't have embedded clock and reset
-  control module, so the proper interface initialization is supposed to be
-  performed by software. There four in- and four outbound iATU regions
-  which can be used to emit all required TLP types on the PCIe bus.
