From d92b0dfc5078aeec869d58372dbda5e16739b8de Mon Sep 17 00:00:00 2001 From: Rajendra Nayak Date: Wed, 14 Dec 2011 17:25:45 +0530 Subject: omap-serial: Add minimal device tree support Adapt the driver to device tree and pass minimal platform data from device tree needed for console boot. No power management features will be suppported for now since it requires more tweaks around OCP settings to toggle forceidle/noidle/smartidle bits and handling remote wakeup and dynamic muxing.
