    cpsw/netcp: cpts depends on posix_timers · 07fef362
    Arnd Bergmann authored
    With posix timers having become optional, we get a build error with
    the cpts time sync option of the CPSW driver:
    
    drivers/net/ethernet/ti/cpts.c: In function 'cpts_find_ts':
    drivers/net/ethernet/ti/cpts.c:291:23: error: implicit declaration of function 'ptp_classify_raw';did you mean 'ptp_classifier_init'? [-Werror=implicit-function-declaration]
    
    This adds a hard dependency on PTP_CLOCK to avoid the problem, as
    building it without PTP support makes no sense anyway.
    
    Fixes: baa73d9e ("posix-timers: Make them configurable")
