Subject: [PATCH 5/6] PPC/MPC5200: re-use the IMX I2C master driver for MPC5200
Date: Fri, 31 Jul 2015 11:03:51 +0200	[thread overview]
Message-ID: <1438333432-10118-6-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1438333432-10118-1-git-send-email-jbe@pengutronix.de>

This IP core is shared between many FSL SoCs. The MPC5200 provides this
core as well.
