1Picochip picoXcell device tree bindings.
2========================================
3
4Required root node properties:
5 - compatible:
6 - "picochip,pc7302-pc3x3" : PC7302 development board with PC3X3 device.
7 - "picochip,pc7302-pc3x2" : PC7302 development board with PC3X2 device.
8 - "picochip,pc3x3" : picoXcell PC3X3 device based board.
9 - "picochip,pc3x2" : picoXcell PC3X2 device based board.
10
11Timers required properties:
12 - compatible = "picochip,pc3x2-timer"
13 - interrupts : The single IRQ line for the timer.
14 - clock-freq : The frequency in HZ of the timer.
15 - reg : The register bank for the timer.
16
17Note: two timers are required - one for the scheduler clock and one for the
18event tick/NOHZ.
19
20VIC required properties:
21 - compatible = "arm,pl192-vic".
22 - interrupt-controller.
23 - reg : The register bank for the device.
24 - #interrupt-cells : Must be 1.
