Subject: usb: xhci-pci: Add DM_FLAG_OS_PREPARE flag
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=e3bbc1f74e05b194cfd2193f93f5c9310fbd3252;p=u-boot.git

usb: xhci-pci: Add DM_FLAG_OS_PREPARE flag

The PCIe bus the controller is connected to might need to be removed
prior the handover. Make sure xhci-pci is also removed so as to avoid
unexpected timeouts or hangs.
