[PATCH V8 1/9] PCI: ecam: move ecam.h to linux/include/pci-ecam.h

Tomasz Nowicki
2016-05-30T15:15:07Z

From: Jayachandran C <jchandra@broadcom.com>

This header will be used from arch/arm64 for ACPI PCI implementation
so it needs to be moved out of drivers/pci.

Update users of the header file to use the new name. No functional
changes.
