31 Phandle to the global status and enable interrupt registers shared
32 between each I2C engine controller instance. It enables the I2C
33 engine controller to act as both a master or slave by being able to
34 arm and respond to interrupts from its engine. Each bit in the
35 registers represent the respective bit position.
