Subject[PATCH v7 0/6] i2c: designware: add I2C SLAVE support
Date
The purpose of this patchset is to enable Linux to be a I2C slave by 
enabling the slave functionality in the designware I2C controller and at
the same time it does some cleaning of the existing code.

The patch 1 is for cleaning and commentary fix.
The patch 2 refactors the original i2c-designware-core and extracts all
master functions to a i2c-designware-master source file as suggested by
Andy Shevchenko when I first submited the update. The patch 3 then
separates the MASTER flow from the common flow.
The patch 4 introduces the SLAVE necessary definitions to the
i2c-designware library and adds a how-to-use example to the designware.txt
in device tree bindings.
The patch 5 adds the necessary functions to give the ability to be a SLAVE
to the controller and for that changes also had to be made in the
Makefile and Kconfig.
The patch 6 enables the SLAVE mode to be detected by the platform module.

The functionality was tested using the hardware independent slave-eeprom
driver based on top of i2c/for-next. The tree I used can be found here:
