Subject: [PATCH v7 0/4] add PCIe driver for Kirin PCIe
Before Version Patches
======================
patch V6
https://www.spinics.net/lists/linux-pci/msg61610.html
patch V4
https://www.spinics.net/lists/linux-pci/msg61406.html
patch V3
https://www.spinics.net/lists/linux-pci/msg61399.html
Changes between V7 and V6
=========================
1. add enumeration log Based on Hikey960 Board with these patches.
2. fix issues as fellows:
(1) delete reduntant blankets in macro defination,
(2) add blank line in kirin_pcie_clk_ctrl function.
(3) Fix compitable property in DT with the SoC name,
for example "hisilicon,kirin960-pcie".
Enumeration log
===============
These test logs come from patches running on Hikey960 Board
