This patch series inherits the patch submitted by Peter.
https://patchwork.kernel.org/project/linux-watchdog/patch/20240430143114.1323686-2-peteryin.openbmc@gmail.com/
Besides, the boot status modififed in the WDT driver
obeys the rules proposed in the OpenBMC.
https://github.com/openbmc/docs/blob/master/designs/bmc-reboot-cause-update.md#proposed-design
Moreover, WDT SW restart mechanism is supported by HW
since AST2600 platform and is also included in this
patch series.

Changes in v2:
  - Support SW restart on AST2600 by default without
    adding any dts property.
