-The subordinate value indicates the highest bus number which can be
-reached downstream though a certain device.
-
-Commit a20c7f36bd3d ("PCI: Do not allocate more buses than available in
-parent")
-ensures that downstream devices cannot assign busnumbers higher than the
-upstream device subordinate number, which was indeed illogical.
-
-By default, dw_pcie_setup_rc() inits the Root Complex subordinate to a
-value of 0x01.
-
-Due to this combined with above commit, enumeration stops digging deeper
-downstream as soon as bus num 0x01 has been assigned, which is always
-the case for a bridge device.
-
-This results in all devices behind a bridge bus to remain undetected, as
-these would be connected to bus 0x02 or higher.
-
-Fix this by initializing the RC to a subordinate value of 0xff, meaning
-that all busses [0x00-0xff] are reachable through this RC.

-parent")
