From 07fef3623407444e51c12ea57cd91df38c1069e0 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 20 Mar 2017 09:58:33 +0100 Subject: [PATCH] cpsw/netcp: cpts depends on posix_timers 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.
