Reboot property to control system reboot on PPC4xx systems:



By setting "reset_type" to one of the following values, the default

software reset mechanism may be overidden. Here the possible values of

"reset_type":



      1 - PPC4xx core reset

      2 - PPC4xx chip reset

      3 - PPC4xx system reset (default)



Example:



		cpu@0 {

			device_type = "cpu";

			model = "PowerPC,440SPe";

			...

			reset-type = <2>;	/* Use chip-reset */

		};

information for devices.



To use GPIO pins as interrupt sources for peripherals, specify the

GPIO controller as the interrupt parent and define GPIO number +

trigger mode using the interrupts property, which is defined like

this:



interrupts = <number trigger>, where:

 - number: GPIO pin (0..31)

 - trigger: trigger mode:

	2 = trigger on falling edge

	3 = trigger on both edges



Example of device using this is:



	funkyfpga@0 {

		compatible = "funky-fpga";

		...

		interrupts = <4 3>;

		interrupt-parent = <&gpio1>;

	};
