1Alphascale asm9260 Watchdog timer 2 3Required properties: 4 5- compatible : should be "alphascale,asm9260-wdt". 6- reg : Specifies base physical address and size of the registers. 7- clocks : the clocks feeding the watchdog timer. See clock-bindings.txt 8- clock-names : should be set to 9 "mod" - source for tick counter. 10 "ahb" - ahb gate. 11- resets : phandle pointing to the system reset controller with 12 line index for the watchdog. 13- reset-names : should be set to "wdt_rst". 14 15Optional properties: 16- timeout-sec : shall contain the default watchdog timeout in seconds, 17 if unset, the default timeout is 30 seconds. 18- alphascale,mode : three modes are supported 19 "hw" - hw reset (default). 20 "sw" - sw reset. 21 "debug" - no action is taken. 22 23Example: 24 25watchdog0: watchdog@80048000 { 26 compatible = "alphascale,asm9260-wdt"; 27 reg = <0x80048000 0x10>; 28 clocks = <&acc CLKID_SYS_WDT>, <&acc CLKID_AHB_WDT>; 29 clock-names = "mod", "ahb"; 30 interrupts = <55>; 31 resets = <&rst WDT_RESET>; 32 reset-names = "wdt_rst"; 33 timeout-sec = <30>; 34 alphascale,mode = "hw"; 35};
