Subject: [PATCH 0/5] arm: ioremap: Remove pci_ioremap_io() and mvebu_pci_host_probe()

This patch series removes ARM specific functions pci_ioremap_io() and
mvebu_pci_host_probe() functions.

pci_ioremap_io() is replaced by standard PCI core function pci_remap_iospace()
and mvebu_pci_host_probe() by standard PCI core function pci_host_probe().

ARM needs custom implementation of pci_remap_iospace() because of
pci_ioremap_set_mem_type() hook used by Marvell Armada 375, 38x and 39x
platforms due to HW errata.

Patch series was compile-tested for all affected platforms and runtime
tested on Armada 385 with pci-mvebu.c driver.

Pali Rohár (5):
  arm: ioremap: Implement standard PCI function pci_remap_iospace()
  PCI: mvebu: Replace pci_ioremap_io() usage by devm_pci_remap_iospace()
  PCI: mvebu: Remove custom mvebu_pci_host_probe() function
  arm: ioremap: Replace pci_ioremap_io() usage by pci_remap_iospace()
  arm: ioremap: Remove unused ARM-specific function pci_ioremap_io()
