Subject: [PATCH v1 0/3] Add Gen4 equalization and margining settings

Add Gen4 specific equalization and rx margining settings. These
settings are inline with respective PHY settings for Gen4
operation. 

In addition, current QCOM EP and RC drivers do not share common
codebase which would result in code duplication. Hence, adding
common files for code reusability among RC and EP drivers.

Shashank Babu Chinta Venkata (3):
  PCI: dwc: refactor common code
  PCI: dwc: add equalization settings for gen4
  PCI: dwc: add rx margining settings for gen4
