  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.
