From 42a7ccef0a06519e2ea0be71d7c0f4ed9198509f Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Wed, 31 Oct 2012 15:32:44 +0000 Subject: [PATCH] ptp: Make PTP_1588_CLOCK select rather than depend on PPS PTP hardware clock drivers that select PTP_1588_CLOCK must currently also select PPS. For those drivers that don't, the user must enable PPS, then enable PTP_1588_CLOCK, then the driver. Simplify things for developers and users by putting this selection in one place.
