However it's different endianness (little-endian) and using PCI driver. To support ENETC PTP driver, ptp_qoriq driver needed to be reworked to make functions global for reusing, to add little- endian support, to add ENETC memory map support, and to add ENETC dependency for ptp_qoriq driver. In addition, although ENETC PTP driver is a PCI driver, the dts node still could be used. Currently the ls1028a dtsi which is the only platform by now using ENETC is not complete, so there is still dependency for ENETC PTP node upstreaming. This will be done in the near future. The hardware timestamping support for ENETC is done but needs to be reworked with new method in internal git tree, and will be sent out soon.
