1 * SBSA (Server Base System Architecture) Generic Watchdog
3 The SBSA Generic Watchdog Timer is used to force a reset of the system
4 after two stages of timeout have elapsed. A detailed definition of the
5 watchdog timer can be found in the ARM document: ARM-DEN-0029 - Server
6 Base System Architecture (SBSA)
9 - compatible: Should at least contain "arm,sbsa-gwdt".
11 - reg: Each entry specifies the base physical address of a register frame
12 and the length of that frame; currently, two frames must be defined,
14 1: Watchdog control frame;
17 - interrupts: Should contain the Watchdog Signal 0 (WS0) SPI (Shared
18 Peripheral Interrupt) number of SBSA Generic Watchdog.
21 - timeout-sec: Watchdog timeout values (in seconds).
23 Example for FVP Foundation Model v8:
26 compatible = "arm,sbsa-gwdt";
27 reg = <0x0 0x2a440000 0 0x1000>,
28 <0x0 0x2a450000 0 0x1000>;
29 interrupts = <0 27 4>;
