When I merged your pci/dwc branch, I noticed what looks like a merge
conflict between these commits:

d123765b58ee ("PCI: dwc: Adjust Kconfig to allow IMX6 PCIe host on IMX7")
1a059d994189 ("PCI: imx: Add support for i.MX8MQ")

d123765b58ee added SOC_IMX7D:

- depends on SOC_IMX6Q || (ARM && COMPILE_TEST)
+ depends on SOC_IMX6Q || SOC_IMX7D || (ARM && COMPILE_TEST)

and 1a059d994189 added SOC_IMX8MQ but dropped SOC_IMX7D again, which looks
like a mistake:

- depends on SOC_IMX6Q || SOC_IMX7D || (ARM && COMPILE_TEST)
+ depends on SOC_IMX8MQ || SOC_IMX6Q || (ARM && COMPILE_TEST)

So my "next" branch[1] (current head 7053eeb009e0) is:

config PCI_IMX6
bool "Freescale i.MX6/7 PCIe controller"
depends on SOC_IMX8MQ || SOC_IMX6Q || (ARM && COMPILE_TEST)
depends on PCI_MSI_IRQ_DOMAIN
select PCIE_DW_HOST

which I think is wrong. Lorenzo, if you update your pci/dwc branch,
I'll rebuild my "next" branch.

If you want to tweak the switch statements and/or IMX8 checks, you
could do that at the same time.
