	  When interrupts fire, the driver's ISR function is being called directly.

	  When interrupts fire, the shared IRQ driver is notified. Then the shared IRQ
	  driver dispatches the interrupt to other drivers.

	  Specify the device name for the shared IRQ driver. It is used to register
	  this driver with the shared IRQ driver, so interrupts can be dispatched
	  correctly.

        Allows the I2C port to be brought up with a default configuration.
        This is useful to set if other drivers depend upon using the I2C bus
        before the application has a chance to custom configure the port.
        Setting this value does not prohibit the application from customizing
        the values later.  Refer to the I2C datasheet for proper values.
