Subject: [PATCH 4/5] arm: shmobile: genmai: adapt dts to use native i2c driver
Date: Tue, 17 Dec 2013 22:44:37 +0100	[thread overview]
Message-ID: <1387316678-10174-5-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1387316678-10174-1-git-send-email-wsa@the-dreams.de>

From: Wolfram Sang <wsa@sang-engineering.com>

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