- Add support for Zephyr I2C target API, which allows device to act as I2C slave device. - Tested using greybus-i2c transport [0]. [0]: beagleboard/greybus-zephyr#95 Signed-off-by: Ayush Singh <ayush@beagleboard.org>
The greybus node acts as a slave i2c device with an address selected by Kconfig variable. The goal is to be able to chain multiple greybus nodes over I2C. Since I2C slave cannot initiate messages to the host, cannot be used with protocols that require the node to initiate messages. Maybe we can use a GPIO to signal to host, but that would not work over grove connector. Signed-off-by: Ayush Singh <ayush@beagleboard.org>
