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>;
} ;
