The laptop contains an embedded controller that provides a set of features: - Battery and charger monitoring - USB Type-C DP alt mode HPD monitoring - Lid status detection - Small amount of keyboard configuration* [*] The keyboard is handled by the same EC but it has a dedicated i2c bus and is already enabled. This port only provides fn key behavior configuration. Add the EC to the device tree and describe the relationship between the EC-managed type-c port and the SoC DisplayPort.
