Show all headers | View raw

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".
