I'm thinking I should drop my pci/host-rcar branch until we
have a fix for this.  It currently contains:

  9ac724f20774 PCI: rcar: Fix I/O offset for multiple host bridges
  7d75b413f5c6 PCI: rcar: Set root bus nr to that provided in DT
  4c22eab88c68 PCI: rcar: Remove dependency on ARM-specific struct hw_pci
  ef18d2e55ea0 PCI: rcar: Make PCI aware of the I/O resources

Is that right?  Last I heard, Linus expects to release v4.3 on Sunday,
so we really don't have much time to sort this out.
