-Spreadtrum SoCs Watchdog timer
-
-Required properties:
-- compatible : Should be "sprd,sp9860-wdt".
-- reg : Specifies base physical address and size of the registers.
-- interrupts : Exactly one interrupt specifier.
-- timeout-sec : Contain the default watchdog timeout in seconds.
-- clock-names : Contain the input clock names.
-- clocks : Phandles to input clocks.
-
-Example:
- watchdog: watchdog@...10000 {
- compatible = "sprd,sp9860-wdt";
- reg = <0 0x40310000 0 0x1000>;
- interrupts = <GIC_SPI 61 IRQ_TYPE_LEVEL_HIGH>;
- timeout-sec = <12>;
- clock-names = "enable", "rtc_enable";
- clocks = <&clk_aon_apb_gates1 8>, <&clk_aon_apb_rtc_gates 9>;
- };
