Subject: [PATCH] Devicetree binding for omap3-serial & bcm2048 combination

Nokia N900 contains bluetooth module connected on serial
port. Unfortunately, serial and bluetooth are rather closely coupled,
so standard serial driver can not be used, and we really don't want
/dev/ttyS1 to be published for internal port of bluetooth
stack... Hence solution below.
