PCIe0 is Gen3 X1 and PCIe1 is Gen3 X2 are added. This series combines [1] and [2]. [1] introduces IPQ5018 PCIe support and [2] depends on [1] to introduce IPQ5332 PCIe support. Since the community was interested in [2] (please see [3]), tried to revive IPQ5332's PCIe support with v2 of this patch series. v2 of this series pulled in the phy driver from [1] tried to address comments/feedback given in both [1] and [2]. 1.
