Subject: [PATCH 11/19] MPC5xxx/serial: provide an easier way to share register description
Date: Tue,  7 Oct 2014 16:22:10 +0200	[thread overview]
Message-ID: <1412691738-11145-12-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1412691738-11145-1-git-send-email-jbe@pengutronix.de>

Separate the register definition to be able to add more SoCs to use them.
