    cpsw/netcp: refine cpts dependency · 504926df
    Arnd Bergmann authored
    Tony Lindgren reports a kernel oops that resulted from my compile-time
    fix on the default config. This shows two problems:
    
    a) configurations that did not already enable PTP_1588_CLOCK will
       now miss the cpts driver
    
    b) when cpts support is disabled, the driver crashes. This is a
       preexisting problem that we did not notice before my patch.
    
    While the second problem is still being investigated, this modifies
    the dependencies again, getting us back to the original state, with
    another 'select NET_PTP_CLASSIFY' added in to avoid the original
    link error we got, and the 'depends on POSIX_TIMERS' to hide
    the CPTS support when turning it on would be useless.
