Subject: [PATCH V2 4/5] arm: shmobile: genmai: adapt dts to use native i2c driver
Date: Wed, 18 Dec 2013 22:32:00 +0100	[thread overview]
Message-ID: <1387402321-21866-5-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1387402321-21866-1-git-send-email-wsa-z923LK4zBo2bacvFa/9K2g@public.gmane.org>

From: Wolfram Sang <wsa-jBu1N2QxHDJrcw3mvpCnnVaTQe2KTcn/@public.gmane.org>

Switch from the gpio-driver to the shiny new native driver. Tested by
accessing the eeprom on the genmai board.
