Add support for enabling the first watchdog pointed via aliases.
DT fragment:
aliases {
...
watchdog0 = &watchdog0;
watchdog1 = &watchdog_lpd;
...
};
dm tree fragment for above configuration with patch applied:
ZynqMP> dm tree
Class index Probed Driver Name
-----------------------------------------
...
watchdog 0 [ ] cdns_wdt | |-- watchdog@ff150000
watchdog 1 [ + ] cdns_wdt | `-- watchdog@fd4d0000
...
dm uclass fragment:
ZynqMP> dm uclass
...
uclass 75: watchdog
0 watchdog@ff150000 @ 7df02f40, seq -1, (req 1)
1 * watchdog@fd4d0000 @ 7df02ff0, seq 0, (req 0)
...
It is visible that index 1 is IP with seq 0 which means that FPD
watchdog (@fd4d0000) is in DT below LPD watchdog (@ff150000).
Till this patch the first watchdog found in DT was used and started
which is not enabling all possible configuration based on user request.
