[PATCH v7 0/5] Introduce SpacemiT K1 PCIe phy support

[Yixun Lan]

Hi Vinod,
 Could you take a look of this series? I suppose patch 1-3 should go via
the generic phy tree, for patch 3, it's already got Neil's R-y [1] which
Alex should collect the tag..
 the Changelog for previous versions are also dropped.. which is bad

anyway, for this series, I've also tested on bananapi with nvme card, so
