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.
So are you ok with this: + depends on PTP_1588_CLOCK_PCH && (PCH_GBE=m || PTP_1588_CLOCK_PCH=y)
or simply like: --- From: Haicheng Li <haicheng.lee@gmail.com>
Fix build error caused by broken PCH_PTP module dependency. The .config is: CONFIG_PCH_GBE=y CONFIG_PCH_PTP=y CONFIG_PTP_1588_CLOCK=m
The build error:
