Before Version Patches ====================== patch V7 https://www.spinics.net/lists/linux-pci/msg61664.html 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 V8 and V7 ========================= 1. Replace 'reset-gpios' of 'reset-gpio' in Documentation. 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". Changes between V6 and V4 ========================= 1. seperate Document from .dtsi patch. 2. fix issues according to review comments from Bjorn Helgaas and Rob Herring: annotation stype, DT node, patch post method and so on.
