Sorry, I'm not sure of the process here... The arm64 patches and
the 'clk: shmobile: r8a7795' patch were only posted as RFC to enable
people to test against a branch in Geert's renesas-drivers.git tree.
The other PCIe patches are in pci-next and have already been pulled
by Linus. I would have thought that we should wait until these are in
your branch before trying to add the arm64 patches.

Do you want me to list the commits needed to get PCIe to work on
Salvator-X, or is it ok to just say pci-next plus any others needed?

Thanks
Phil
