From debeaf6c2ded82bea65c1a487fb629fb0d2bb66f Mon Sep 17 00:00:00 2001 From: Barry Song Date: Mon, 30 Jul 2012 13:29:30 +0800 Subject: ARM: PRIMA2: delete redundant codes to restore LATCHED when timer resumes The only way to write LATCHED registers to write LATCH_BIT to LATCH register, that will latch COUNTER into LATCHED.e.g. writel_relaxed(SIRFSOC_TIMER_LATCH_BIT, sirfsoc_timer_base + SIRFSOC_TIMER_LATCH); Writing values to LATCHED registers directly is useless at all.
