Subject: [PATCH v5 0/6] PCI: qcom: Add support for Glymur PCIe Gen5 x4 and
 Gen4 x2

Glymur is the next generation compute SoC of Qualcomm. This patch series
aims to add support for the fourth, fifth and sixth PCIe instance on it.
The fifth PCIe instance on Glymur has a Gen5 4-lane PHY and fourth, fifth
and sixth PCIe instance have a Gen5 2-lane 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.
