* SBSA (Server Base System Architecture) Generic Watchdog The SBSA Generic Watchdog Timer is used to force a reset of the system after two stages of timeout have elapsed. A detailed definition of the watchdog timer can be found in the ARM document: ARM-DEN-0029 - Server Base System Architecture (SBSA) Required properties: - compatible: Should at least contain "arm,sbsa-gwdt". - reg: Each entry specifies the base physical address of a register frame and the length of that frame; currently, two frames must be defined, in this order: 1: Watchdog control frame; 2: Refresh frame. - interrupts: Should contain the Watchdog Signal 0 (WS0) SPI (Shared Peripheral Interrupt) number of SBSA Generic Watchdog. Optional properties - timeout-sec: Watchdog timeout values (in seconds). Example for FVP Foundation Model v8: watchdog@2a440000 { compatible = "arm,sbsa-gwdt"; reg = <0x0 0x2a440000 0 0x1000>, <0x0 0x2a450000 0 0x1000>; interrupts = <0 27 4>; timeout-sec = <30>; };
