From 6620377e4b8be3c232c59d673efcd673c30bc69f Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Fri, 13 Jun 2014 22:55:49 +0200 Subject: sunxi: Add i2c support Add support for the i2c controller found on all Allwinner sunxi SoCs, this is the same controller as found on the Marvell orion5x and kirkwood SoC families, with a slightly different register layout, so this patch uses the existing mvtwsi code.
