From 4499ce42935db68debba0a2d2ab8280627e4b692 Mon Sep 17 00:00:00 2001 From: Suman Anna Date: Fri, 5 Feb 2010 17:20:26 -0600 Subject: omap: mailbox: correct OMAP4 SIDLEMODE logic OMAP4 mailbox has a different MAILBOX_SYSCONFIG register. There is now no AutoIdle. The SIDLEMODE bits have been right-shifted by 1 bit and now occupy bits 2 & 3.
