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@40310000 { compatible = "sprd,sp9860-wdt"; reg = <0 0x40310000 0 0x1000>; interrupts = ; timeout-sec = <12>; clock-names = "enable", "rtc_enable"; clocks = <&clk_aon_apb_gates1 8>, <&clk_aon_apb_rtc_gates 9>; };
