		Picochip picoXcell device tree bindings.
		========================================

		Required root node properties:
		- compatible:
		- "picochip,pc7302-pc3x3" : PC7302 development board with PC3X3 device.
		- "picochip,pc7302-pc3x2" : PC7302 development board with PC3X2 device.
		- "picochip,pc3x3" : picoXcell PC3X3 device based board.
		- "picochip,pc3x2" : picoXcell PC3X2 device based board.

		Timers required properties:
		- compatible = "picochip,pc3x2-timer"
		- interrupts : The single IRQ line for the timer.
		- clock-freq : The frequency in HZ of the timer.
		- reg : The register bank for the timer.

		Note: two timers are required - one for the scheduler clock and one for the
		event tick/NOHZ.

		VIC required properties:
		- compatible = "arm,pl192-vic".
		- interrupt-controller.
		- reg : The register bank for the device.
		- #interrupt-cells : Must be 1.
