Is the > config comming from snps,dw-pcie? Oops..It's my mistake. Just needs to put three reg. Elbi : External local Bus interface register. Dbi : Data bus interface register.(Control register.) Config : for configuration space. "config" can be removed. Because it's not Exynos specific, synopsys's Required property. > >> +- reg-names: Must be "elbi", "phy" and "dbi" for each regs > > Again, three here, four in example.
