The imx23-olinuxino board has an i2c interface exposed on UEXT connector. This patch provides the generic devicetree infrastructure for a follow-up patch to add support to the actual board files. Tested all three possible pin groups with MOD-LCD1x9 from Olimex. This patch is based on work by Fadil Berisha with his permission. However all bugs are mine.
