Subject: [PATCH 0/3] PCI: endpoint: Add endpoint restart management support

Add new functions to manage recovery of configuration for endpoint controller
and restart the controller when asserting bus-reset from root complex (RC).

This feature is only available if bus-reset (PERST#) line is physically
routed between RC and endpoint, and the signal from RC also resets
the endpoint controller.

This series is only for UniPhier PCIe endpoint controller at this point.

Kunihiko Hayashi (3):
  PCI: endpoint: Add 'started' to pci_epc to set whether the controller
    is started
  PCI: endpoint: Add endpoint restart management
  PCI: uniphier-ep: Add EPC restart management support
