Cover letter [PATCH v4 0/5] i2c: designware: Add slave support
The purpose of this patch is to enable Linux to be a I2C slave by enabling the slave functionality in the designware I2C controller. The patch refactors the original i2c-designware-core and extracts all master functions to a i2c-designware-master source file as suggested by Andy Shevchenko. It also creates a i2c-designware-slave source file and keeps the common functions in the i2c-designware-src source file. For that changes also had to be made in the Makefile and Kconfig.
The driver instantiates in slave or master mode by checking the compatible string of the device tree (see devicetree/bindings/i2c/i2c-designware.txt). ACPI is not supported.
The functionality was tested using the hardware independent software backend slave-eeprom driver.
