This patchset:

    (1)Export "arch_timer_get_rate" in arm_arch_timer.c for the
    other drivers, like SBSA watchdog driver

    (2)Introduce Documentation/devicetree/bindings/watchdog/sbsa-gwdt.txt
    for FDT info of SBSA Generic Watchdog, and give two examples of
    adding SBSA Generic Watchdog device node into the dts files:
    foundation-v8.dts and amd-seattle-soc.dtsi.

    (3)Introduce "pretimeout" into the watchdog framework, and update
    Documentation/watchdog/watchdog-kernel-api.txt to introduce:
        (1)the new elements in the watchdog_device and watchdog_ops struct;
        (2)the new API "watchdog_init_timeouts".

    (4)Introduce ARM SBSA watchdog driver:
        a.Use linux kernel watchdog framework;
        b.Work with FDT on ARM64;
        c.Use "pretimeout" in watchdog framework;
        d.In first timeout(WS0), do panic to save system context;
        e.Support geting timeout and pretimeout from parameter and FDT
          at the driver init stage.

Looks all good to me, please add

Acked-by: Arnd Bergmann <redacted>

for patches 1-6.

    (5)Parse SBSA Generic Watchdog Structure in GTDT table of ACPI,
    and create a platform device with that information.
    This platform device can be used by This Watchdog driver.

This needs to be reviewed by someone who understands ACPI.
