From 53fe628558bab9a11050ba067a09442c92dca6bb Mon Sep 17 00:00:00 2001 From: Shiraz Hashim Date: Fri, 13 Jul 2012 00:11:10 -0700 Subject: [PATCH] Input: spear_keyboard - fix clock handling during suspend/resume SPEAr keyboard should normally disable clock during suspend and enable it during resume. For cases where it is expected to act as a wakeup source the clock can remain in the same state i.e. kept enabled if it is being used.
