Help¶

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.

Help¶

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