From 504926df6df5383cad25146de3ed0a45e02c0901 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 28 Apr 2017 17:03:58 +0200 Subject: [PATCH] cpsw/netcp: refine cpts dependency 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.
