Subject: [PATCH v2 0/4] AM64: Add PCIe bindings and driver support

AM64 uses the same PCIe controller as in J7200, however AM642 EVM
doesn't have a clock generator (unlike J7200 base board). Here
the clock from the SERDES has to be routed to the PCIE connector.
This series provides an option for the pci-j721e.c driver to
drive reference clock output to the connector.

v1 of the patch series can be found @ [1]

Changes from v1:
*) Fixed missing initialization of "ret" variable in the error path.

Kishon Vijay Abraham I (4):
  dt-bindings: PCI: ti,j721e: Add binding to represent refclk to the
    connector
  dt-bindings: pci: ti,j721e: Add host mode dt-bindings for TI's AM64
    SoC
  dt-bindings: pci: ti,j721e: Add endpoint mode dt-bindings for TI's
    AM64 SoC
  PCI: j721e: Add support to provide refclk to PCIe connector
