Since the DW PCIe common code now supports the IP-core version
auto-detection there is no point in manually setting the version up for the
controllers newer than v4.70a. Seeing Tegra 194 PCIe Host and EP
controllers are based on the DW PCIe v4.90a IP-core we can freely drop the
dw_pcie.version field initialization.

Folks, I don't have Tegra 194 PCIe hw instance to test it out. Could you
please make sure this patch doesn't brake anything?

Hi,
I tried to apply the series https://patchwork.kernel.org/project/linux-pci/list/?series=653624 on top of linux-next and ran into conflicts. Could you please tell me the minimum set of patches to be taken?

Thanks,
Vidya Sagar
