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.
