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]
v2 of the patch series can be found @ [2]
v3 of the patch series can be found @ [3]

Changes from v3:
*) Added Reviewed by from Rob
*) Incorporated Krzysztof Wilczyński comment on DT binding documentation
*) Fixed "warn: missing error code 'ret'"

Changes from v2:
*) Fix DT binding documentation suggested by Rob

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