Kishon Vijay Abraham I 129714f773 usb: core: hcd: Add support for deferring roothub registration ... commit a44623d927 upstream. It has been observed with certain PCIe USB cards (like Inateck connected to AM64 EVM or J7200 EVM) that as soon as the primary roothub is registered, port status change is handled even before xHC is running leading to cold plug USB devices not detected. For such cases, registering both the root hubs along with the second HCD is required. Add support for deferring roothub registration in usb_add_hcd(), so that both primary and secondary roothubs are registered along with the second HCD. This patch has been added and reverted earier as it triggered a race in usb device enumeration. That race is now fixed in 5.16-rc3, and in stable back to 5.4 commit 6cca13de26 ("usb: hub: Fix locking issues with address0_mutex") commit 6ae6dc22d2 ("usb: hub: Fix usb enumeration issue due to address0 race") CC: stable@vger.kernel.org # 5.4+ Suggested-by: Mathias Nyman <mathias.nyman@linux.intel.com> Tested-by: Chris Chiu <chris.chiu@canonical.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Link: https://lore.kernel.org/r/20220510091630.16564-2-kishon@ti.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2022-06-09 10:25:14 +02:00
