    +Xilinx AXI/PLB soft-core watchdog Device Tree Bindings
    +---------------------------------------------------------
    +
    +Required properties:
    +- compatible : Should be "xlnx,xps-timebase-wdt-1.00.a" or
    + "xlnx,xps-timebase-wdt-1.01.a".
    +- reg : Physical base address and size
    +
    +Optional properties:
    +- clock-frequency : Frequency of clock in Hz
    +- xlnx,wdt-enable-once : 0 - Watchdog can be restarted
    + 1 - Watchdog can be enabled just once
    +- xlnx,wdt-interval : Watchdog timeout interval in 2^<val> clock cycles,
    + <val> is integer from 8 to 31.
    +
    +Example:
    +axi-timebase-wdt@40100000 {
    + clock-frequency = <50000000>;
    + compatible = "xlnx,xps-timebase-wdt-1.00.a";
    + reg = <0x40100000 0x10000>;
    + xlnx,wdt-enable-once = <0x0>;
    + xlnx,wdt-interval = <0x1b>;
    +} ;
