[PATCH 0/2] phy: qcom: qmp-pcie: Add support for Glymur PCIe Gen4x2 PHY

[Abel Vesa]

The Glymur platform comes with two PCIe Gen4 2-lanes controllers.

Add support for their PHYs and document the compatible.

This patchset depends on the following:

[PATCH 1/2] dt-bindings: phy: sc8280xp-qmp-pcie: Document Glymur PCIe Gen4 2-lanes PHY

[Abel Vesa]

The fourth and sixth PCIe instances on Glymur are both Gen4 2-lane PHY.
So document the compatible.
