From 51d070afd6f927752c76a0cc537c73737578bb93 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Thu, 27 Jan 2011 02:52:55 -0700 Subject: [PATCH] OMAP2/3: PM: remove unnecessary wakeup/sleep dependency clear The OMAP2 and OMAP3 PM code clears clockdomain wakeup and sleep dependencies. This is unnecessary after commit 6f7f63cc9adf3192e6fcac4e8bed5cc10fd924aa ("OMAP clockdomain: initialize clockdomain registers when the clockdomain layer starts") which clears these dependencies during clockdomain init.
