From: Ben Hutchings Date: Thu, 19 Dec 2013 19:21:14 +0000 (+0000) Subject: tile_net: Always enable PTP clock support on TILE-Gx X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=69317a5351022e1b207131e7cccc78f261ace9ac;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git tile_net: Always enable PTP clock support on TILE-Gx All other net drivers with PTP support enable it unconditionally. Make tile_net consistent with this. Signed-off-by: Ben Hutchings Acked-by: Chris Metcalf Signed-off-by: David S.
