Here is an updated to describe the registers' purpose, and function. description: Phandle to the global status and enable interrupt registers shared between each I2C engine controller instance. It enables the I2C engine controller to act as both a master or slave by being able to arm and respond to interrupts from its engine. Each bit in the registers represent the respective bit position.
