picoxcell: support for Picochip picoxcell devices
picoXcell is a family of femtocell devices with an ARM application processor and picoArray DSP processor array. This patch adds support for picoXcell boards to be booted using the device tree registering the VIC's, UART's and timers. v3: - fixup vic compatible string in binding v2: - cleanup empty mach headers - convert to of_platform_populate() - simplify uncompress.h - split vic node into 2 devices - add missing __initconst attributes Signed-off-by: Jamie Iles <jamie@jamieiles.com>

+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.
