Chromebooks have an Embedded Controller (EC) that is used to implement various functions such as keyboard, power and battery. The AP can communicate with the EC through different bus types such as I2C, SPI or LPC. The cros_ec mfd driver is then composed of a core driver that register the sub-devices as mfd cells and provide a high level communication interface that is used by the rest of the kernel and bus specific interfaces modules. Each connection method then has its own driver, which register with the EC driver interface-agnostic interface. Currently, there are drivers to communicate with the EC over I2C and SPI and this driver adds support for LPC.
