Hi,
I am running linux-next 20140805 on a imx6q-sabresd board and noticed
the following error:
root@freescale /$ dmesg | grep pci
[ 0.168095] imx6q-pcie 1ffc000.pcie: missing *config* reg space
[ 0.501019] imx6q-pcie 1ffc000.pcie: phy link never came up
[ 0.501579] imx6q-pcie 1ffc000.pcie: PCI host bridge to bus 0000:00
This 'missing *config* reg space' was introduced by:
commit 4dd964df36d0e548e1806ec2ec275b62d4dc46e8
Author: Kishon Vijay Abraham I <kishon@xxxxxx>

PCI: designware: Look for configuration space in 'reg', not 'ranges'
The configuration address space has so far been specified in *ranges*,
however it should be specified in *reg* making it a platform MEM resource.
Hence used 'platform_get_resource_*' API to get configuration address space
in the designware driver.

Wouldn't this break dt compatibility?
