Subject: PCIe patch for ARM64

Hi

I am developing PCIe root port driver for Xilinx device. We have used following patch for ARM64 bit support "https://lkml.org/lkml/2014/7/3/764". The link explains it as temporary patch and main line will be updated soon with those changes. We have not seen the changes till now. Can you let us know when we can expect the changes in mainline? We are planning to push our drivers to mainline.

Thanks & Regards
Bharat Kumar Gogada

Please have a look to the latest kernel and try to see what is
available for ARM64 PCIe.

You may see drivers/pci/host/pci-xgene.c as reference.

I see that there is already a driver for xilinx PCIe controller with
ARM platform.
drivers/pci/host/pcie-xilinx.c

If it is the same device on ARM64, then you need to take similar
approach what is being discussed
for designware on ARM64.
