Hello, this patch set adds support for the I2C Transaction Generator which offloads CPU from managing I2C transfer step by step. This feature is currently only available on the I2C controller IP embedded in the Armada XP SoC. That's why usage of this mechanism is optional and activated through device tree. The first patch modifies the driver itself and should go through i2c subsystem. Due to the recent changes in i2c-mv64xxx.c file caused by Russell King's fixes, I based this patch on the for-next branch of the i2c git repository. The second patch updates the device tree to be able to use this new feature and should go through mvebu subsystem. The 2 patches are independents for building or even at runtime, but of course we need both of them to be able to use the I2C Transaction Generator on the Armada XP SoC.
