Please adapt the name of the binding as well, and name it snps-dwc-pcie.txt
for instance, to match the change in the driver and in the binding.

Thanks for changing it here.

but please also change the example and the .dts files to match.
It should say here

		compatible = "samsung,exynos5440-pcie", "snps,dwc-pcie";

as now required by the binding.
