Subject: [PATCH] Devicetree binding for omap3-serial & bcm2048 combination
Date: Wed, 28 Jan 2015 10:35:01 +0100 [thread overview]
Message-ID: <20150128093501.GA17338@amd> (raw)
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.
