From 2fde9668b47e74d1bfad2f1688a4481e6b966d04 Mon Sep 17 00:00:00 2001 From: David Hendricks Date: Thu, 2 May 2013 16:47:54 -0700 Subject: exynos5250/snow: deprecate time.h time.h We Hardly Knew Ye. This deprecates time.h which is currently only used by Exynos5250 and Snow. The original idea was to try and unify some of the various timer interfaces and has been supplanted by the monotonic timer API. timer_us() is now obsolete. timer_start() is now mct_start() and is exposed in exynos5250/clk.h.
