about the patch " [v2] arm64: pci: add support for pci_mmap_page_range"

Hi Jerin & Will,

Sorry to trouble you!

I found your patch https://patchwork.codeaurora.org/patch/2059/ and thought it's
helpful as many dev tools will access the resourceX file for different devices/drivers, 
e.g nvme-cli for NVMe.

As for the ?legacy /proc interface?, I think it should be another topic: you have to
modify the proc for pci and handle various tools broken. But for exposing resourceX, it does work. 
I wonder why this patch is not accepted into upstream? Or newer version is available?
