X-Git-Tag: v6.11-rc1~97^2~17^2~1 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b8747e10fde9573834b9f320593422e37af1af97;p=thirdparty%2Flinux.git PCI: layerscape-ep: Use the generic dw_pcie_ep_linkdown() API to handle Link Down event Now that dw_pcie_ep_linkdown() is available, use it. This also handles the reinitialization of DWC non-sticky registers in addition to sending the notification to EPF drivers.
