Subject: [PATCH v3 0/3] PCI: dra7xx: Support PCIe x2 lane mode

Previous version of the patch series can be found here [1]

Patch series adds support to enable x2 lane mode in dra74/dra76 and
dra72 based boards in pci-dra7xx driver. 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.
