This is actually no different from vcc3v3-pcie regulator?

It seems that there is no need to define additional data-lanes when
the pcie3x1 node is not enabled, and phy-supply seems unnecessary on
this board.

Excuse me, can you try the patches I posted? Lspci can recognize
pcie3x2 normally, but I don't have a spare nvme hard drive right
now to test if it works.

Thanks, Chukun
