driver: gpio: add gpio driver support in NPCX series Add gpio support for Nuvoton NPCX series. This CL includes: 1. Add GPIO device tree declarations. 2. Introduce wui_maps property in yaml file to present relationship between Wake-Up Input (WUI) and 8 IOs belong to the device. 3. Zephyr GPIO api implementation. 4. GPIO callback functions implementation with MIWU api functions. 5. Overlay file for gpio basic tests Signed-off-by: Mulin Chao <MLChao@nuvoton.com>

driver: i2c: add i2c support in npcx series. The NPCX SMB modules provides full support for a two-wire SMBus/I2C synchronous serial interface. Each SMBus/I2C 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. In NPCX7 series, the SMB5 and SMB6 modules contain a two-way switch to support two separate SMBus/I2C buses (ports) with one SMB module (controller) Please refer Section 4.7.2 in the datasheet. In order to support it, this CL seperates the i2c driver into port and controller drivers. The controller driver is in charge of i2c module operations and internal state machine. The port driver is in charge of pin-mux and connection between Zehpyr i2c api interface and controller driver. All of modules have separate 32-byte transmit FIFO and 32-byte receive FIFO buffers. These FIFO buffers reduce firmware overhead during long SMBus transactions by allowing the Core to write or read more than one data byte at a time to/from the SMB module. The CL also includes: — Add npcx i2c port/controller device tree declarations. — Zephyr i2c api implementation. — Add "i2c-0" aliases in npcx7m6fb.dts for i2c test suites.

dts: npcx7m6fb: define the port as i2c bus rather than the controller The npcx7m6fb dts defines i2c controller and ports, where the controller is a property in the port node definition and the device nodes should be defined as subnodes of the port. This changes the binding definitions to reflect that, defining the port as an i2c-controller so that in can inherit sub-nodes for i2c devices, and the controller as a generic node.
