From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH net 1/3] cpsw/netcp: cpts depends on posix_timers Date: Fri, 16 Dec 2016 10:19:57 +0100 Message-ID: <20161216092017.2560717-1-arnd@arndb.de> Cc: Arnd Bergmann , Grygorii Strashko , Thomas Gleixner , John Stultz , =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= , WingMan Kwok , Nicolas Pitre , netdev@vger.kernel.org, linux-kernel@vger.kernel.org To: "David S.

[-Werror=implicit-function-declaration] It really makes no sense to build this driver if we can't use PTP, so it's better to go back to 'select PTP_1588_CLOCK' but instead add a dependency on POSIX_TIMERS.
