IT7230: touch button controllers

T7230 supports max. 13 touch keys with a post-processing with CDC, and it can automatically calibrate and compensate the front-end CDC values for environmental changes.

The IT7230 supports one I2C compatible interface to communicate with the host. It also supports two address
select pins to specify the device ID addresses. Through this interface, the host can program the internal
controlled registers to configure this chip to meet users’ requirements. Furthermore, GPIO and current-control
functions are supported to indicate the specific status or LED dimming by the user’s definition.
