*Nuvoton NPCX embedded controller (EC) I2C driver*

Type: ``bool``

Help

.. code-block:: none

    Enable support for NPCX I2C driver. The NPCX SMB/I2C modules provides
    full support for a two-wire SMBus/I2C synchronous serial interface.
    Each interface is a two-wire serial interface that is compatible with
    both Intel SMBus and Philips I2C physical layer. There are 8 SMBus
    modules and 10 buses in NPCX7 series.

    This option enables the I2C driver for NPCX family of
    processors.
    Say y if you wish to use I2C modules on NPCX MCU.
