From f18cc2ff5e18e8eb6df5284866331ef4a2db58d6 Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Fri, 23 Oct 2009 19:03:50 +0300 Subject: OMAP3: PM: Disable interrupt controller AUTOIDLE before WFI OMAP interrupt controller goes to unknown state when there is right combination of l3,l4 sleep/wake-up transitions, l4 autoidle in interrupt controller and some interrupt. When this happens, interrupts are not delivered to ARM anymore and ARM will remain in WFI (wait for interrupt) until interrupt controller is forced to wake-up (i.e. lauterbach).
