Subject: [PATCH v6 0/6] i2c: designware: add I2C SLAVE support
Date: Wed, 15 Feb 2017 12:22:09 +0000 [thread overview]
Message-ID: <cover.1487009294.git.lolivei@synopsys.com> (raw)
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:
