[PATCH 0/2] i2c-mv64xxx: Add I2C Transaction Generator support

From: Gregory CLEMENT
Date: Fri Jun 07 2013 - 11:43:25 EST


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

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

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.
