Signed-off-by: Harini Katakam --- v5 changes: No changes v4 changes: - Change name of property "reset" to "reset-on-timeout". - Use cdns compatible string in example. - Improve description of clocks and interrupts. v3 changes: - Change reset property type and improve description. - Improve description of clocks and interrupts. - Use watchdog@ in the example. - Use only cdns compatible string for now. v2: No changes --- .../devicetree/bindings/watchdog/cadence-wdt.txt | 24 ++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 Documentation/devicetree/bindings/watchdog/cadence-wdt.txt diff --git a/Documentation/devicetree/bindings/watchdog/cadence-wdt.txt b/Documentation/devicetree/bindings/watchdog/cadence-wdt.txt new file mode 100644 index 0000000..c3a36ee --- /dev/null +++ b/Documentation/devicetree/bindings/watchdog/cadence-wdt.txt @@ -0,0 +1,24 @@ +Zynq Watchdog Device Tree Bindings +------------------------------------------- + +Required properties: +- compatible : Should be "cdns,wdt-r1p2". +- clocks : This is pclk (APB clock). +- interrupts : This is wd_irq - watchdog timeout interrupt. +- interrupt-parent : Must be core interrupt controller. + +Optional properties +- reset-on-timeout : If this property exists, then a reset is done + when watchdog times out. +- timeout-sec : Watchdog timeout value (in seconds). + +Example: + watchdog@f8005000 { + compatible = "cdns,wdt-r1p2"; + clocks = <&clkc 45>; + interrupt-parent = <&intc>; + interrupts = <0 9 1>; + reg = <0xf8005000 0x1000>; + reset-on-timeout; + timeout-sec = <10>; + }; -- 1.7.9.5
