Subject: [PATCH 0/2] phy: qcom: qmp-pcie: Add support for Gen4 4-lane mode
 for X1E80100

On both QCP and CRD board currently supported upstream, the NVMe sits
on the PCIe 6. Until now that has been configured in dual lane mode
only. The schematics reveal that the NVMe is actually using 4 lanes.
So add support for the 4-lane mode and document the compatible for it.
