From c16c3f672defb7aca1276065375fe1ee5ca003dc Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Thu, 11 Dec 2008 16:46:57 +0200 Subject: [PATCH] OMAP3: PM: MPU and CORE should stay awake if there is CAM domain ACTIVE MPU and CORE should stay awake if there is CAM domain ACTIVE. This is because that module doesn't have wake-up capability. This should replace the patch that is currently in the PM branch.
