It introduces new compatible strings in order to enable x2 lane mode support. Changes from v2: *) Have a single syscon dt property for configuring x2 lanes *) Fix minor comments given by Lorenzo (falling back to 1 lane mode, remove unused structure member). Changes from v1: *) Added ti prefix to syscon-lane-conf and syscon-lane-sel as suggested to Rob *) Merged "PCI: dwc: dra7xx: Add support for SoC specific compatible strings" and "PCI: dwc: pci-dra7xx: Enable x2 mode support" into a single patch. *) Fixed $subject as suggested by Bjorn *) Added x2 lane mode support for DRA72x The dts changes and phy changes will be sent as a separate series.
