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. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
