From 200a274f359995df239a46ac8f15ccd48261a458 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Wed, 5 Mar 2014 18:24:11 -0600 Subject: [PATCH] ARM: OMAP3: fix iva mmu programming issues The IVA MMU is not functional when used through the hwmod and omap_device layers. Add fixes to clockdomain and hwmod data to have it functional. The hwmod changes are needed to enable the clock, and the SWSUP change is needed to wakeup the domain because the power domain is programmed to be in RET, and there is no automatic power domain switching to ON.
