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.

This enables support for systems based on the Picochip picoXcell
family of Femtocell devices. The picoxcell support requires device tree
for all boards.
