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.
