PTP clock driver for FSL DPAA

[Y.b. Lu]

Hi Richard,

I'm going to make a PTP clock driver patch for FSL DPAA ethernet controller. (drivers/net/ethernet/freescale/dpaa/)
Actually the 1588 timer module on FSL DPAA is same with the one on FSL eTSEC in hardware.(whose PTP clock driver is drivers/net/ethernet/freescale/gianfar_ptp.c)

So there are two options for me I think.
Option #1, just make a dpaa_ptp.c driver which will be almost same with gianfar_ptp.c.
Option #2, try to reuse gianfar_ptp.c driver by reworking it as a common driver, renaming it, and putting it to a common place (drivers/ptp/ or still drivers/net/ethernet/freescale/).

I'd like to ask your suggestion.
Thanks a lot.

Best regards,
Yangbo Lu
