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.

Thank you for your feedback,
