This patch series enables hardware time stamping and a PTP hardware clock
for mx6 ENET controller.
Frank Li (4):
net: fec: move fec_enet_private to header file
ARM: dts: imx6q: Add ENET PTP clock pin and clock source
ARM: imx6q: Set enet tx reference clk from anatop to support 1588
FEC: Add time stamping code and a PTP hardware clock

All applied to net-next.
Please make sure your changes are in sync with Ben's PTP/PPS
Kconfig changes of today, and send me any changes if necessary.

Thank you very much.
I checked Ben's patch, which not affect FEC.
best regards

Maybe just remove the Kconfig line "select PPS".
Thanks,

More than that: FEC should select PTP_1588_CLOCK, FEC_PTP should be
removed and all the conditional code made unconditional. Alternately,
if that would cost too much (in terms of performance or memory) on some
systems where the driver is used, FEC_PTP should default to 'y'.

Bd description will be difference between no PTP and PTP hardware,
So driver will not incompatible at two kind of hardware.
I can set it default is Y at MX6 platform.
