··· 1 - Spreadtrum SoCs Watchdog timer 2 - 3 - Required properties: 4 - - compatible : Should be "sprd,sp9860-wdt". 5 - - reg : Specifies base physical address and size of the registers. 6 - - interrupts : Exactly one interrupt specifier. 7 - - timeout-sec : Contain the default watchdog timeout in seconds. 8 - - clock-names : Contain the input clock names. 9 - - clocks : Phandles to input clocks. 10 - 11 - Example: 12 - watchdog: watchdog@40310000 { 13 - compatible = "sprd,sp9860-wdt"; 14 - reg = <0 0x40310000 0 0x1000>; 15 - interrupts = <GIC_SPI 61 IRQ_TYPE_LEVEL_HIGH>; 16 - timeout-sec = <12>; 17 - clock-names = "enable", "rtc_enable"; 18 - clocks = <&clk_aon_apb_gates1 8>, <&clk_aon_apb_rtc_gates 9>; 19 - };
