-* 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>;
-};
