Messages in this thread | | This patches follows the merged patchset that refactors I2C Designware and enables it to have I2C support.
The patch 1 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 2 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:
