Watchdog can handle callbacks - VirtualManager can attach to the tick. This should simplify the logic.
Watchdog can tick on its own using tickers.
VirtualWatchdog uses attach to get a callback when Watchdog ticks - to process own
linked list of virtual watchdogs.
Watchdog should be usable on it's own - kicking it via ticker. No Virtual involved.
VirtualWatchdog as well - services should use this one to have multiple one in the system.
There's WatchdogManager - basically internal class to manage ticker for Watchdog.
Refactor old Watchdog (it was not a driver) to become VirtualWatchdog.
This is software virtual watchdog. This it the primary used watchdog in user application.
VirtualWatchdog: has-a watchdog. Initializes hw watchdog - start it when first used, stops it when there is no more VirtualWatchdog in the system -
list is empty.
Adding also check to watchdog to make sure there is only one in the system - runtime error if multiple objects created to already
running hw watchdog.
Watchdog is hardware driver. It interacts with HAL - provides wrapper to interact with the peripheral.
Provides basic functionality: start/stop, get timeout/max timeout.
It is automatically kicked by a timer, according to the timeout set in ctor.
Update the watchdog timing requirements:
1. The watchdog should trigger at, or after the timeout value.
2. The watchdog should trigger before twice the timeout value.
Use a SERIAL_FLUSH_TIME_MS value consistent with other tests.
