++description:
++ The JH7100 and JH7110 watchdog both are 32 bit counters. JH7100 watchdog
++ has only one timeout phase and reboots. And JH7110 watchdog has two
++ timeout phases. At the first phase, the signal of watchdog interrupt
++ output(WDOGINT) will rise when counter is 0. The counter will reload
++ the timeout value. And then, if counter decreases to 0 again and WDOGINT
++ isn't cleared, the watchdog will reset the system unless the watchdog
++ reset is disabled.
