From 2800971f731e4491b71f44bf311452ab0f94a062 Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Fri, 17 Jul 2015 16:08:01 -0500 Subject: [PATCH] ARM: dts: AM33xx: Add ti,mbox-send-noirq to wkup_m3 mailbox Add ti,mbox-send-noirq to wkup_m3 mailbox so that messages using wkup_m3 mailbox are sent without triggering any further interrupts. This is needed to achieve lower power numbers during CPU idle on AM33xx.
