[PATCHv6 03/28] PCI: mobiveil: Fix PCI base address in MEM/IO outbound windows

From: Hou Zhiqiang <Zhiqiang.Hou@nxp.com>
Date: 2019-07-05 10:07:13
Also in: linux-arm-kernel, linux-pci, lkml
Subsystem: pci native host bridge and endpoint drivers, pci subsystem, the rest · Maintainers: Lorenzo Pieralisi, Krzysztof Wilczyński, Manivannan Sadhasivam, Bjorn Helgaas, Linus Torvalds

The outbound memory windows PCI base addresses should be taken
from the 'ranges' property of DT node to setup MEM/IO outbound
windows decoding correctly instead of being hardcoded to zero.

Update the code to retrieve the PCI base address for each range
and use it to program the outbound windows address decoders
