[PATCH v1 0/5] powerpc/pci: PCI slot unified reset

[Gavin Shan]

The patchset corresponds to skiboot changes, which manages PCI slots
in a unified way: OPAL APIs used to do slot reset, power management,
presence status retrival. The patchset shouldn't be merged before
the OPAL firmware counterpart is merged.

The kernel changes have been split into 2 parts: (A) Use the unified
PCI slot reset OPAL API - this patchset; (B) Changes to rpaphp.ko to
support PCI slot hotplug via sysfs entries for PowerPC PowerNV platform.

This patchset affects EEH, PCI reset logics, which is used mainly by
VFIO. A couple of cases have been tested out on P7/P8 boxes and looks
good: EEH on PowerNV, EEH support for guest, PCI passthrou.

Gavin Shan (5):
  powerpc/powernv: Use PCI slot reset infrastructure
  powerpc/powernv: Refactor ioda_eeh_reset()
  powerpc/powernv: Avoid do complete reset for twice
  powerpc/powernv: Issue fundamental reset if required
  powerpc/powernv: Drop opal_pci_reinit()
