As for this specific patch:

quoted

-	depends on PTP_1588_CLOCK_PCH
+	depends on PTP_1588_CLOCK_PCH = PCH_GBE

This is not the correct way to ensure that the module'ness of one
config option meets the module'ness requirements of another.
The correct way is to say something like "&&  (PCH_GBE || PCH_GBE=n)"

This case is a little bit tricky than usual, with PCH_PTP selected,
the valid config would be either "PTP_1588_CLOCK_PCH=PCH_GBE=m" or
"PTP_1588_CLOCK_PCH=PCH_GBE=y", and PTP_1588_CLOCK_PCH depends on
PCH_GBE.

And a simple "&& PCH_GBE" should accomplish this, no?
