Glymur is the next generation compute SoC of Qualcomm. This patch series
aims to add support for the fifth PCIe instance on it. The fifth PCIe
instance on Glymur has a Gen5 4-lane PHY. Patch [1/4] documents PHY as a
separate compatible and Patch [2/4] documents controller as a separate
compatible. Patch [3/4] describles the new PCS offsets in a dedicated
header file. Patch [4/4] adds configuration and compatible for PHY.

The device tree changes and whatever driver patches that are not part of
this patch series will be posted separately after official announcement of
the SOC.
