* 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>;
|
|
};
