From 48a00e7fe9a6abeedb62c99ca7b7860754aae3d8 Mon Sep 17 00:00:00 2001 From: Jouni Hogander Date: Tue, 22 Sep 2009 16:46:56 -0700 Subject: [PATCH] omapfb: dispc: enable wake up capability Without wakeup enable omap doesn't wake up on dispc interrupts. This causes problems in a case where mpu is in sleep state and dispc interrupt fires.
