Whew, it took a long time to pound that through my thick skull :)
I think patches 1 and 3 are already in v4.5-rc1, and I applied patches 2
and 4 to my for-linus branch as below. Please double-check and make sure
for-linus has everything you want. I'll ask Linus to pull that before
v4.5.

PCI: rcar: Add gen2 device tree support for r8a7793
Add "renesas,pci-r8a7793" as a compatibility string for
"renesas,pci-rcar-gen2".
This doesn't change the driver, so it does nothing by itself. But it
does mean that checkpatch won't complain about a future patch that adds
"renesas,pci-r8a7793" to a DT, which helps ensure that shipped DTs use
documented compatibility strings.
