Subject: [PATCH v2 0/5] Add support for Axis, ARTPEC-8 PCIe driver

This v2 patchset is improvement several review comments received from patchset v1.

Main changes since v1 [1]:
-'make dt_binding_check' result improvement
-Add the missing property list
-improvement review comment of Krzysztof on driver code
-change folder name of phy driver to axis from artpec

--------------------------------------------------------------
This series patches include newly PCIe support for Axis ARTPEC-8 SoC.
ARTPEC-8 is the SoC platform of Axis Communications.
PCIe controller driver and phy driver have been newly added.
There is also a new MAINTAINER in the addition of phy driver.
PCIe controller is designed based on Design-Ware PCIe controller IP
and PCIe phy is desinged based on SAMSUNG PHY IP.
It also includes modifications to the Design-Ware controller driver to 
run the 64bit-based ARTPEC-8 PCIe controller driver.
It consists of 6 patches in total.

This series has been tested on AXIS SW bring-up board 
with ARTPEC-8 chipset.
